-----------------------------------------------------------------------------------------
2005-06-20 pwessel
* mgd77/mgd77.c: Now applies recalculation of fields requested by E77 flags
as part of reading netcdf mgd77+ files.

2005-06-13 pwessel
* grdimage.c: Failed to determine boundary of projected grid with enough precision.
* misc/gmtstitch.c: Check to see if format was set was wrong.
* mgd77/mgd77track.c: Missing newline after last source line

2005-06-12 pwessel
* examples: Added ex27 for plotting img files and ex28 for plotting UTM
* psbasemap.c: The syntax for the -L option had to change since one could
not easily use the :label: specification if the coordinates
were given in dd:mm[:ss] format. A new syntax has been
implemented where one or more +?[args] strings are appended
after the required parameters.
* pscoast.c: Same.
* gmt.h, gmt_init.c: Modified special checks for FreeBSD by also considering _AMD64_

2005-06-11 pwessel
* mgd77/mgd77sniffer.c: Bitwise assignment error was deactivating other fields when
depth field was missing from a cruise. Another bitwise error
was overwriting E77 nav flags when navigation was found on land
Updated sample grid function to handle longitudes for img files
* mgd77/mgd77.c: Index array error resulting in wrong IGRF start and stop
years was fixed.
2005-06-09 pwessel
* xyz2grd.c: For -E under Windows we used fscanf with a pointer from GMT DLL
which would fail for mysterious reasons

2005-06-05 pwessel
grdfilter.c: Complained if -R was used and xmin was < h.xmin for full
360-range grid.

2005-06-03 pwessel
* gmt_init.[ch]: gmtdefs.encoding.name could be freed even if never allocated.
* examples/ex27: New example showing how to plot Mercator *.img grids.

2005-06-02 pwessel
* pslib.c: ps_polygon can only split line when rgb[0] == -1 not < 0
since -3 now means to use a fill pattern.
* pstext.c: Enhanced -Z+ option expects z-level values in 3rd column

2005-06-01 pwessel
* Win installer: Now installs the GMT include files so users can build their own
programs that use the GMT libs

2005-05-29 pwessel
* grdreformat.c: There is no longer a share/conf/gmt_formats.conf so the
grdreformat usage message crashes. Introduced new file
grdreformat.h created by GNUmakefile to include this info.

2005-05-27 pwessel
* grdfilter.c: The -D5 did not initialize xscale so filter search box was
set to region width which typically is much larger. The bug
did not affect the results but unnecessarily increased runtime.
2005-05-27 remko
* pslegend.c: Let N (number of columns) also affect the printing of labels
* pslegend.txt: Made clear that N only affects the printing of symbols and labels

2005-05-22 pwessel
* gmt_map.c, gmt_init.c: Added support for enhanced -E option for 3-D perspective
views which allows the specification of a fixed point (needed for
creating animations). Updated all programs to use the new option
and added updated man page and synopsis to all programs.

2005-05-20 pwessel
* gmt_io.c: Did not properly apply PLOT_DEGREE_FORMAT=ddd.x for decimal degrees
* gmt_map.c: Determining where parallels and meridians intersected the map
boundary where susceptible to roundoff for very small regions
* gmt_plot.c: Checked for map jumps even for non-periodic map boundaries.

2005-05-19 pwessel
* pscoast.c: The -Q option should not require -J
* pstext.c: Cannot remove blank lines when in paragraph mode as those
lines signal the end of each paragraph.
2005-05-18 remko
* configure.ac: Version updated to 4.3.2. Added CVS_VERSION switch.
* src/gmt_version.h.in: Add date and time to CVS version string.

-----------------------------------------------------------------------------------------
2008-05-15
* tar 4.3.1 made and released via email
-----------------------------------------------------------------------------------------

2005-05-15 pwessel
* xyz2grd.c: The -S option incorrectly insisted that -G needed to be set.

2005-05-12 remko
* conf/gmtdefaults_{SI,US}.in: Renamed from .gmtdefaults_* (no longer hidden)
* configure.ac, gmt_init.c: Changed accordingly
* Makefile: "make install-data" now copies only the appropriate directories
and file from the share directory, i.e. not CVS directory, and
.cvsignore and *.in files.
* src/makefile: Link libgmtps.$(SL) and libpsl.$(SL) to appropriate libraries.
* src/x2sys/makefile: No need for linking libx2sys.$(SL) against netCDF.

2005-05-12 pwessel
* /*.c: Some supplement programs had a mix of GMT_fopen and fread
which usually fails under Windows when a dynamic DLL is used.

2005-05-09 remko
* gmt_support.c: Allow a little more slop in determining whether primary tick
is at same location as secondary tick.

2008-05-08 pwessel
* grd2xyz.c: For -E: The test for dx == dy was susceptible to round-off

2008-05-07 remko
* gmt_io.c (GMT_nc_input): Would not read all columns when no variable names given.

2008-05-06 pwessel
* gmtselect.c: Did not like a variable number of columns. Now OK if ASCII
i/o and at least 2 (3 with -Z) columns are found.
* gmt_mgg2_header.c: Passed 2nd, 3rd arguments to fread in the wrong order, thus
failed to read GRD98 grids.
* gmt_init.c: Now, media size Custom_WxH can use W and H in inch, cm, or m
by appending i, c, or m to each dimension.

2008-05-05 pwessel
* psxyz.c: Memory problem: Since realloc does not initialize we
must explicitly set the pointer in the PSXYZ_DATA1 structure
to NULL since we later use the pointer to determine if we
need to free allocated memory.
* project.c: Same for the 2 pointers in the PROJECT_DATA structure.

2008-05-03 pwessel
* psxy.c: The -D option erroneously gave error when used properly.

-----------------------------------------------------------------------------------------
2008-05-01
* tar 4.3.0 made and released via email
-----------------------------------------------------------------------------------------

2008-05-01 pwessel
* gmt_map.c: GMT_grd_project did not check if x_proj was NaN before trying
to add/sub 360 degrees, hanging under Windows.

2008-05-01 remko
* ps2raster.c: When encountering BoundingBox: (atend), skip to the end.
* grdsample.c: Did not allocate enough memory, with crashes resulting.
* share/conf/*.orig: Replaced by *.in, and processed by ./configure using AC_SUBST
* guru/GMT_share_files_ascii.lis: Removed share/conf files.
* guru/GMT_src_files_ascii.lis: Added share/conf/*.in files.
* configure.ac: ---"---, including setting EPS in BOTH US and SI when --enable-eps
* guru/gmtguru.macros.orig, GNUmakefile: Added GMT_OTHER to add other flags to configure.

2008-04-29 pwessel
* grdview.c: Clarified that -T cannot take -JZ|z, fixed clipping.

2008-04-28 pwessel
* mgg/mgd77togmt.c: Did not initialize MGG_SHAREDIR path.

2008-04-28 remko
* GMT_eckert.sh: Removed. Was not used by anything.
* GMT_gall_stereo.sh: Added example for -JCyl_stere.
* GMT_Chapter_6*.tex: Added more information on optional -J parameters. Added some
historical background.
* examples, scripts: Removed options in -J when same as default.

2008-04-26 pwessel
* README etc: Updated to reflect recent changes such as only *.bz2 archives
and references to Windows installers.
* grdview.c: The -Qc option failed to set the "build image" flag and produced
garbage surface tiles. Also, -T[s] produced polygons that were
not checked for wrapping at a periodic map boundary.

2008-04-25 pwessel
* x2sys: Moved *.def to share/x2sys
* mgd77/mgd77sniffer.c: Cumulative fixes & updates since August 2007:
Added -K option to flip navigation flags (if extreme positions
cause checking to flag good records rather than bad).
Added -D[x]r option, where x is any preexisting -D option.
Appending r tells sniffer to use all records in sniffer output
rather than omitting records flagged with bad navigation.
Moved speed checking algorithm to precede any other analysis of
mgd77 data records, including regression checking. This allows
extreme nav errors to be flagged and ignored in later analysis.
Modified speed checking algorithm to compare the current nav fix
to the previous good nav fix, rather than just the previous nav fix.
This does a better job of flagging the correct fix when excessive
speeds are found. Previously the current flag was compared to the
previous flag and whenever excessive speed was computed the current
record was flagged. This lead to flagging good records at times when
it was the previous record that was bad.
Modified manage to accept flags with NaN time stamps.
Changed speed check from speed > max_speed to fabs (speed) > max_speed
Bug in E77 output causing distance to be printed when cruises have time stamps
Track outliers in decimate function, if more than 5% outliers use the
maximum possible MGD77 values for the 2D bin table in the decimate function.
Blocked decimation algorithm when dumping values, gradients, etc., and when
non-regression related warnings are selected (see -W option). Removed bug
from excessive offset from grid print command.
Fixed negative array index bug in precision check code
Fixed an E77 RLS print bug
Fixed memory deallocation bug - was GMT_free on out[rec] - now on out[curr]
Added anomaly recalculation toggle to E77
Use double instead of float for everything but the GMT grids
Added anomaly sign tracking also fixed e77 scale and icept for A option
also cleared up kludgy code in grid and ship regression section

2008-04-24 remko
* ps2raster: Use PID to augment the file names of temporary files.
This is not totally secure, but the alternative, mkstemp, is not
standard enough (not ISO C90).
Option -N has become obsolete. Use -S and/or -Te instead.

2008-04-22 pwessel
* psxy.c: Now will properly clip polygon outline and not draw it along clipped border.
* configure.ac: Added support for --enable-mex-mdir=dir and --enable-mex-xdir=dir
to override the Matlab/Octave preferred paths for local *.mfiles
and *.mex functions.
* install_gmt: Now uses these new variables when running configure.

2008-04-21 pwessel
* mapproject.c: -G+ will compute distance between coordinates in first 4 columns

2008-04-19 pwessel
* configure.ac, src/makegmt.macros.in, mex/makefile: Added support for --enable-octave
as an alternative to --enable-matlab

2008-04-16 remko
* psxy.c, psxyz.c: Two bug fixes in both programs.
- If first symbol in list with size was not circle, it got rejected.
- When sizes of -Sr or -Sj were read from list, they were always inches.

2008-04-15 remko
* pslib.c, PSL_*.ps: Renamed a few PostScript commands; reduced prologues in size.
* gmt_support.c (GMT_just_decode): Bug fix: was defaulting to BC, instead of BL.
Also reduced to two arguments (second being default justification).
* ps{image,legend}.c: Reduced arguments in GMT_just_decode.
* ps{scale,text}.c: ---"---
* gmt_support.h: ---"---
* gmt_plot.[ch] (GMT_timestamp): Added "justify" argument to specify justification of
the time stamp box. Provided by gmtdefaults or -U option.
* gmt_init.c: Added justification to GMT_UNIX_POS. Is now //.
Also added to -U option parsing.
Fully backwards compatible with previous versions (default just=BL).
* gmtdefaults.txt: ---"---
* explain_-U.txt: ---"---
* common_options.txt: ---"---
* gmt{,_globals,_common.h}: ---"---
* .gmtdefaults_*.orig: ---"---. Set PS_IMAGE_COMPRESS = lzw.
* .gmtdefaults4.doc, .gmtdefaults_test: Now created on the fly from system defaults file.

2008-04-14 pwessel
* psxy[z].c: Drawing arrows with -SvS and time-coordinates did not work as 2nd time
coordinate did not get processed properly.

2008-04-13 pwessel
* grdview.c: The facade (-N) outline was drawn with contour pen. Now use -Wf to change
the facade pen from its default value.
2008-04-11 pwessel
* x2sys/x2sys_binlist.c: Could create bad bins because of incorrect reallocation of memory.
* mex/*.c: No longer need to include matrix.h separately. This helps octave compilation.

2008-04-09 remko
* gmt_init.c (GMT_timestamp): Added new gmtdefaults value UNIX_TIME_FORMAT, which sets the format for
the time string in the GMT time stamp (-U option). The default is
"%Y %b %d %H:%M:%S", which is what was printed up to now, except that
%e (which is not supported by ISO C90) is replaced by %d.
* gmtdefaults.txt: ---"---
* gmt{,_globals.h}: ---"---
* gmtdefaults_*.orig: ---"---
* gmt_plot.c: Use gmtdefs.unix_time_format to format the time stamp. This also requires
the time stamp box to size with the time string and the additional label
to move. Tweaked the placement of the strings a bit (better vertical
placement and relative horizontal placement using spaces).

2008-04-07 remko
* gmt_grdio.c: Did not yet properly combine ?varname=suffix on output grid.
* ps2raster.c: Security improvements: (1) Replaced tmpnam by mktemp, as tmpnam provides
a limited number of temp file names. (2) Run commands using system(cmd)
directly and remove file using remove(file), instead of creating a
script first.

2008-04-05 pwessel
* gmt_map.c: Fixed final bug in GMT_radial_clip. Also, GMT_world_map should be
FALSE for azimuthal projections. This fixes the -JA -JE pscoast bugs.

2008-04-05 remko
* gmt_map.c, gmt_proj.c: Fixed bug in azimuthal equal area projection that had the
horizon shifted from where it ought to be.
* *.txt: Added more short explanations on input and output grid formats.
In some man pages -F was explained instead of -f.
* GMT_Chapter_4.tex, GMT_Appendix_B.tex: Added information on -bic (netCDF tables).

2008-04-04 pwessel
* gmt_stat.c: Bug in GMT_median would sometime give subtle mistakes, most noticeable
when only a few values were passed to the function. Traced to the use
of size_t variables in expressions that should yield a negative value.

2008-04-04 remko
* GNUmakefile: Removed creation of *.tar.gz and GMT_src.zip.
* configure.ac: CFLAGS, CPPFLAGS, LDFLAGS as set by user is ADDED to anything configure
dreams up. Neither OVERRULES the other.
NETCDF_LIB and NETCDF_INC can be used to set netCDF locations separately.
Create versioned shared libraries on Linux.
* */makefile: Changes made accordingly.
* job04c.*: Renamed from job4c.*
* run_example_tests.sh: New test script of example files
* run_*_tests.sh: Avoid excessive error messages when compare fails on missing files, etc.
* ps2raster.c: Always translate and/or rotate EPS output to origin. Not only when
in concert with other formats. This makes -P -Te work as -P -Tef.

2008-04-02 remko
* gmt_grdio.c: GMT_is_*_grid now works on header struct. GMT_grd_get_format also strips
off ? and stores it in header->varname.
* gmt_nc.c: When writing netCDF grid ? can be used to assign variable name
and long_name attribute.

2008-04-02 pwessel
* gmt_map.c: The radial clipping would sometimes add arcs using the arc that
is > 180 degrees.
* x2sys/x2sys_put.c: Wrong test when replacing older track info lead to dbase loss.

2008-04-01 pwessel
* examples/ex19/*: Next GMT conference is now in 2009.
* gmt_support.c: Made GMT_polygon_is_open tolerant of round-off and if
polygon is not open set last to exactly equal first point.

2008-04-01 remko
* gmt_proj.c: Avoid error in GMT_lamb_sph when lat is 90 degrees.

2008-03-29 pwessel
* pslib.[ch]: Like in gmt, use PS_exit instead of exit to avoid Matlab shutdown.

2008-03-26 pwessel
* gmt_grdio.c: Now the grd i/o support the GMT_[DATA|IMG|GRID]DIR environment settings.
* grdinfo.c: Reports actual path to the file (may change if GMT_GRIDDIR is involved).

2008-03-25 pwessel
* pscontour.c: Must deallocate *ind memory according to which function was used
* triangulate.c: Same. Only affects Windows's insane memory management.

2008-03-24 pwessel
* gmt_map.c: Added new rectangular clip function using Sutherland/Hodgman algorithm
in order to fix incorrect results in grdlandmask.
* grdblend.c: Did not pick up node registration before calculating output grid size.

2008-03-24 remko
* gmt_io.c: Implemented -b[i|o]c[/...] option to indicate input is netCDF.

2008-03-23 pwessel
* ALL: More solid 64-bit support after full cleansing with -Wconversion. All 26
examples runs clean in both 32-bit and 64-bit mode as do the entire GMT
documentation.

2008-03-22 remko
* gmt_nc.c: Moved GMT_nc_get_att_text to gmt_io.c so it can be used more generally.
* gmt_io.c: Implemented GMT_nc_input to support reading netCDF column data (tables).
This also required changes to GMT_fopen and making GMT_fclose a real routine
rather than a macro.
* gmt_io.h, gmt_globals.h: Changed accordingly.
* misc/nc2xy.c: More space for long_name and units.

2008-03-22 pwessel
* *.[ch]: Experimental support for full 64-bit computing with introduction of 8-byte
integers instead of 4-byte.

2008-03-19 remko
* gmt_map.c (GMT_map_clip_path): In polar projection, step size for drawing clip path
was wrong, resulting in missing wedge in donut shape.

2008-03-15 pwessel
* gmt_support.c: GMT_get_annot_label did not properly honor the ddd.xx setting
* pstext.c: In -D, if /dy is not given it is set equal to dx
* psxy.c: Same. Clarified both usage and man pages.

2008-03-13 remko
* gmt_support.c: GMT_hsv_to_rgb, GMT_rgb_to_hsv, GMT_check_hsv now uses hsv[]
instead of h, s, v, in accordance with similar routines.
GMT_getrgb and GMT_gethsv can read hexadecimal color codes,
which need to start with #, e.g. #ff0000 for red.

2008-03-11 pwessel
* grdgradient.c: With -D -S the slopes were not set to NaN if data were NaN
* gmt_map.c: Bug in map clipping for -JG
* gmt_support.c: Improve map annotation for general perspective projection
Added support for annotations for -JF gnomonic for global maps.
* gmt_proj.c: Clip path for general perspective projection was not closed.

2008-03-11 remko
* bin/gmtlogo: Pushed text back up into 2 x 1 inch box. Put in isolation mode
* src/Colors.txt: Reorganized list of RGB colors and names.
* gmt_color{name,_rgb}.h: Removed from CVS. Now created from Colors.txt
* doc/sctipts/GMT_RGBchart.sh: Added GMT logo. All sizes horizontal.
* src/gmtcolors.txt: New man page with color information.
* src/Grdformats.txt: Renamed from share/conf/gmt_formats.conf

2008-03-09 pwessel
* pstext.c: Parsing of -C complained about % sign

2008-03-09 remko
* gmt_init.c, gmt_globals.h: Moved GMT_N_MEDIA and GMT_N_UNIQUE to gmt_dimensions.h, which
is automatically created.
* gmt_media_name.h, gmt_media_size.h: Added "statement" and "tabloid" sizes
* doc/scripts/GMT_RGBchart.sh: Script to create RGB color tiles added to CVS
* doc/GMT_Appendix_I.tex: Added RGB chart
* www/gmt/doc/pdf/GMT_RGBchart_*.pdf: Added A4, Letter and Ledger sized RGB charts

2008-03-07 remko
* ex11/job11.*: Added R, G, B, H, S, and V arrows.
* doc/scripts/GMT_color_interpolate.sh: New example on color palette interpolation.
* doc/scripts/GMT_App_M_1.sh: Make sure titles get centered on color bars.
* doc/fig/{gimp*,hsv-cone}.png: New imagery for Appendix I
* doc/GMT_Appendix_I.tex: Completely revamped Appendix I
* doc/GMT_Chapter_7.tex: Removed some ugly orphans.
* doc/GMT_version.tex.in: Removed "Version" from \GMTDOCVERSION
* doc/GMT_Frontmatter.tex: Added some more acknowledgments
* gmtdefaults.txt: Explained COLOR_MODEL better.
* gmt_support.c: Avoid small color values. -1e-15 will look like h-s-v.
A + in the gmtdefaults COLOR_MODEL definition overrules interpolation
mode specified in cpt file.

2008-03-06 pwessel
* binned_GSHHS*.cdf: Added two missing barrier islands along Long Island, NY
to the GSHHS database. Updated next GSHHS version number to 1.10.
* grdcontour.c: Recognize if no contours can be found inside -L range and exit.

2008-03-05 remko
* grdinfo.c: Implemented Welford (1962) algorithm for more precise one-pass
computation of mean and sum of squares.
* grdedit.c: Adjust z_min and z_max when changing add_offset or scale_factor.
* gmt_grdio.c: Changed "Latitude", "Longitude" and "Time" to lowercase only.
* gmt_nc.c: Use coordinate variables lon(lon), lat(lat) or time(time) when
appropriate. When updating: need to remove "add_offset" when 0 and
"scale_factor" when 1.
* grd2xyz.c: Do not abort with -R exceeds grid; simply output common region.

2008-03-04 remko
* grdmath.c, gmtmath.c: Implemented Welford (1962) algorithm in KURT, SKEW and STD operators
for more precise one-pass computation of mean and sum of squares.

2008-02-29 remko
* makefile: More sure-fire way to install libraries. Also give shared libs mode 755.
* isogmt.in, isogmt.txt: Script to run GMT in isolation mode introduced
* GMT_App_P_{1,2}.sh: Isolation mode examples
* GMT_Appendix_P.tex: Added description of isolation mode

2008-02-28 pwessel
* mgd77/mgd77info.c: Same issue as minmax that was fixed on 2008-01-31.

2008-02-27 remko
* gmt_io.[ch], gmt_calclock.[ch]: Removed GMT_dt_from_usert, GMT_usert_from_dt, GMT_dtime.
These were remnants of a time that internal time representation was entirely
in rata die numbers. Since computations are done extensively with relative
time (in doubles) keeping the conversion double-to-double became non-sensical.

2008-02-25 pwessel
* gmt_io.c: Now skips blank lines that has leading whitespace. Function
GMT_is_a_blank_line (char *line) is now used wherever ascii
input is processed.
* pscontour.c: -T option was susceptible to infinite loop if bad record was found.

2008-02-25 remko
* configure.ac, src/makefile, src/x2sys/makefile, src/mgd77/makefile, makegmt.macros.in:
Shared libraries made easy: now set LIBEXT=a for static libraries and
LIBEXT=$(SL) for shared libraries. Works also in supplements.
* nc2xy.c: Time coordinate recognized as such. Relative time output according
to TIME_UNIT and TIME_EPOCH set in .gmtdefaults.
* gmt_grdio.c: Fixed 3 bugs in GMT_decode_grd_h_info that caused problems parsing -D
option. Explicitly exclude = sign from becoming separator.

2008-02-24 remko
* grd2xyz.txt, xyz2grd.txt: Added information on using TIME COORDINATES.
* gmt.h, gmt_globals.h: Time system now fully defined in struct gmtdefs.time_system.
* gmt_calclock.c: ---"---
* gmt_init.c, gmt_init.h: GMT_get_time_system and GMT_init_time_system_structure now use
time_system as argument so that not only the internal time system
defined in gmtdefs.time_system can be parsed.
Need to move these functions to gmt_support.c?
GMT_get_time_system can now also deal with "TIME_UNIT since TIME_EPOCH".
'T' no longer required in epoch string.
That means TIME_SYSTEM = "days since 2000-01-01 12:00" works.
* gmt_grdio.c: Now reuses GMT_get_time_system and GMT_init_time_system_structure.

2008-02-24 pwessel
* gmt_*.c: Made sure functions call GMT_exit and not exit when quitting. Only main
programs call exit.
* pslib.c: Bug in ps_shorten_path lead to SEGV when path resulted in a single point.

2008-02-22 remko
* ex*/job*.sh: Prepared for inclusion in documentation (instead of job*.csh)
* doc/GNUmakefile: Updated accordingly
* doc/GMT_Chapter_7.tex doc/GMT_Tutorial.tex: Switched from C shell to Bourne shell

2008-02-22 pwessel
* psrose.c: Added new -F option to disable the plotting of the scale bar.

2008-02-21 pwessel
* pslib.c: Fixed error in applying pstext's -Dj/ shift in paragraph mode (-M).
* mgd77/mgd77list.c: Added -Ga|b to limit output to a certain record # range

2008-02-21 remko
* test/psscale/ages.sh: Fixed errors in geological names. Put some bars upside down.
* psscale.c: Bug fixes: (1) Inverted vertical scale, when using filled rectangles:
Colours remained in the original order. (2) Inverted vertical or horizontal
scale, when using rectangles with gradients: Size of rectangles followed
original order, not inverted. (3) In reverse mode, -Eb was plotting
foreground triangle, -Ef background triangle.
* doc/GMT_Appendix_M.tex, doc/scripts/GMT_App_M_2.sh: Figure added to App M to illustrate uses
of psscale.

2008-02-20 remko
* gmt_init.c: TIME_SYSTEM has become a shortcut for a combination of TIME_EPOCH and
TIME_UNIT. When used, set gmtdefs.time_unit and gmtdefs.epoch immediately.
No longer appears in .gmtdefaults4 file. No more predefined scale,
rata_die, etc for time systems. Those are determined from
gmtdefs.time_{unit,epoch} by GMT_init_time_system_structure instead.
Bug fix: 'c' for seconds was not recognized as TIME_UNIT (expected 's',
which is kept for backwards compatibility).
* gmt_time_systems.h: Removed. Information merged into gmt_init.c.
* gmt_calclock.h: GMT_GCAL_EPOCH has become obsolete.
* gmt_globals.h: Changed default time_epoch from 2000-01-01 midnight to noon.
GMT_time_system is no longer an array. time_system removed from gmtdefs.
* gmt.h: Removed name, epoch, unit as part of GMT_TIME_SYSTEM struct. Epoch and

* gmt_mgg2_header2.[ch]: NGDC has updated the GRD98 format so that the previously unused variable
unused1 now will hold cell registation (1 = pixel, 0 = gridline), thus
extending the GRD98 format to pixel grids as well.
Fixed a bug in which the grid format type (12) got reset to 0, thus
making grdinfo report the wrong file format.
* grdfft.c: -D and -I option could have junk in the parameter arrays if more than
one such argument was given.

while -G- -G+ will turn off fill or reset to default (in -M).

2006-11-08
* gmt_init.c: 2006-10-03 fix for Windows was botched; format should have been %c not %s
* psxy.c: When used with -S but no -W or -G given, only set default -W if -M not used.

Fixed time-scaling bug on input (was always seconds).
* gmt_io.c: One can now add suffixes 'g' or 'd' to denote geographic coordinates.

-R[g|d] forces geographical, so that -JX does not need extra d
When absolute or relative time is used in -R, -JX does not need extra T or t
-R[g|d]w/e/s/n[r] also sets geographical.

in the selected system (RGB or HSV only). Default remains RGB.
PS_COLOR has been extended to accept HSV as well (only applies to
polygon, symbol, pen, and text colors, not images.)

2006-03-10

at all. Thanks go to Masakazu Higaki for providing the fix.

2006-03-07
* gmt_io.c: For years, date in format needs %5d, not %4d since we might have
a negative year (months and days, however, only need %2d).
With %4d, dates like -4321-01-01 was read as -432-01-01.

2006-03-06
* gmtdefaults.c: Added support for PS_VERBOSE, which controls the writing of
comments to the PostScript output stream [FALSE].
