Replaced "break" statements when parsing options with "return TCL_ERROR."  This
might lead to partially modified objects coming from bad commands.
Added layer member to TkGeoMapObj.  It does not do anything yet.
Updated man pages.

full command line and not just a chunk.
Reduced geolinearray subcommands to "fmxdr", "fmbin", "fmascii", "fmlist",
"rm", and "list".  The rest of the geolinearray commands are subcommands
to array commands.
(POTENTIAL INCOMPATIBILITY)

8 Jul 2002
In tclGeoLineArray.c, separated subcommand processing for "geolinearray" command
and lineArray commands.  All tclGeoLineArray callbacks now take the entire
command line instead of just a chunk.

10 Jul 2002
Removed tkGeoMapWdg from pkgIndex.tcl

12 Jul 2002
Deleted TclGeoLineArrayNameUsed and TclGeoLineArrayName procedures.

by deleting the array's Tcl command.
(POTENTIAL INCOMPATIBILITY)
"geolinearray list" prints names of linearrays in the current namespace only.
(POTENTIAL INCOMPATIBILITY)
Removed userCnt member from GeoLnArr struct and associated functions.  Added
GeoLnArrFree function.  GeoLnArrDestroy now returns void.
Added TclGeoLnArrAddDeleteCallback and TclGeoLnArrCnxDeleteCallback procedures.

13 Jul 2002
Deleted TkGeoMapCenter, TkGeoMapCenter, TkGeoMapLatLonToMap, and

Lines hash table of TkGeoMap structure now uses ONE_WORD_KEYS.  Keys are
pointers to TclGeoLineArray structures, values are pointers to TkGeoMapObj
structures.
Added calls to TclGeoLnArrAddDeleteCallback and TclGeoLnArrCnxDeleteCallback
to geolinearray draw and erase procedures.

Cardinal directions should be spelled out now (at least enough for unambiguous
abbreviation).
(POTENTIAL INCOMPATIBILITY)

25 Jul 2002

them into compliance with the "Tcl/Tk Engineering Manual."
Eliminated TclMsg interface.

28 Jul 2002
Replaced TclSubCmd struct's with separate arrays for subcommand names and
callback procedures.  Tcl_GetIndexFromObjStruct was putting garbled strings

29 Jul 2002
In "geolinearray fmascii", if descriptor is given as a number of lines, drop
the final newline on the last line.

TclGeoProjDefaultId now returns the default projection identifier instead of
copying it into char * argument.
Removed support for OLD_CANVAS definition.

no more need for separate interfaces since there is only the canvas item
now.

2 Aug 2002
Added TclGeoLnArrName procedure.
Replaces TkGeoMapUpdateLines and TkGeoMapUpdatePlaces with updateGeoMap, which
updates everything.
Eliminated TkGeoMapFree and geoMapUpdate procedures.  Their code is used only
once, so now it is in line.

Created GeoMapKey structure and makeKey and getGeoMapFromObj functions.

4 Aug 2002
Changed variable names for coordinates for consistency.  Now prefix 'map'
denotes map coordinates and 'dw' denotes drawable coordinates.  Map coordinates
refers to lat-lon's that have been projected and rotated but not scaled.  In
other words, they are coordinates on a plane, cone, cylinder, or some other
2D figure tangent to or near the spherical Earth.

6 Aug 2002
Added canvas tags option.
Bug fix to 'geoplace nearest' callback procedure.

7 Aug 2002
Modified drawDot procedure so that a dot is drawn whenever the command is
called, unless explicit overridden with "-size 0".  If no command line options
are given, there is no further processing.  Fields in the GeoMapPlace structure
are left alone, where before they were set to defaults.

TclGeoProjCnxUpdateTask.  Eliminated reference counts for TclGeoProj structure.
Now a projection is said to be in use if there are update tasks assigned to it.

11 Aug 2002
Moved GeoProj struct into geoProj.h.  Added prefixes to structure type names
to prevent interference with other declarations.
Changed proj member of TclGeoProj structure from struct GeoProj * to
struct GeoProj (i.e. it is now a struct, not a pointer).
(Potential incompatibility) Removed GeoProjCopy and copy callback.

12 Aug 2002
Eliminated geoProjFreeAll function.

script that identifies required links automatically (assuming commands are
listed on one line with a '\-' in the NAMES section).

qualified.  This prevents TclUtilFullName from being called with its return
value as its name argument.

20 Jan 2003
Replaced "-style" option for geolinearray item with "-dash" and "-dashoffset"
using code lifted from Tk source.  Some of this uses Tk struct members
directly, so it might require modification in future versions.

(Bug fix) Added some gsave and grestore calls to geolinearray Postscript code.
Changed -dotsize option from TK_CONFIG_INT to TK_CONFIG_PIXELS.
Replaced calls to XFillRectangle with XFillArc so dots on geolinearray items
are circular.

22 Jan 2003
(Bug fix) Added calls to XFillRectangle for 1 pixel dots, because XFillArc
does not go down to that size.
Allowed negative line width or "none" to indicate no lines.

a namespace, qualifiers must be added explicitly.
"geomap::place new" and "geomap::place set" command no longer automatically
add namespace qualifiers.
Eliminated TclUtilFullName function.

and rotation.3.

3 Feb 2003
Merged tclgeography.3 tclgeolinearray.3 tclgeoplace.3 tclgeoproj.3 man pages
into tclgeomap.3.  This makes the man page hierarchy match the header file
hierarchy.

10 Feb 2003
Removed TclgeomapPlace parameter from Tclgeomap_PlaceUpdateProc and
Tclgeomap_PlaceDeleteProc function types.

14 Feb 2003
(Potential incompatibility) Eliminated Tclgeomap_DefaultProjId function.
(Potential incompatibility) "geomap::projection new" is gone.
"geomap::projection" creates a command used to access and use the projection
whose subcommands are "set", "info", "fmlatlon", and "tolatlon".  The
projection is deleted by deleting its command.

Eliminated tagOrId argument from setproj, which now gets configuration from
internal variables set with cvs_config.
(bug fix) geoLnArrToPoint procedure assumes unfilled line is always a line,
never a closed polygon, even if its endpoints match.

25 Mar 2003
Removed the cvs_new procedure.  Now the configuration is created if needed by
the cvs_config procedure.

1 Apr 2003
(Potential incompatibility) Deleted TclgeomapCurrNmSpc function.  Deleted
functions that depend on it: 'geomap::lnarr list' and 'geomap::place list'.
Modified functions that might use it: 'geomap::place azrng', 'geomap::place
distance', 'geomap::place inrange', and 'geomap::place nearest'.

Deleted -clip option.

17 Apr 2003
(bug fix) Now take account of border when computing canvas center (when

tkgeomap_procs.  They have been superseded by the igeomap megawidget.

12 May 2003
Added xytolatlon and latlontoxy methods to igeomap megawidget.

21 May 2003
Added bogus geomap_place item so latlontoxy and xytolatlon will always work.
Added -frozen option.

25 May 2003

(bug fix) Check for map point gone nowhere before generating postscript for a
place.
(bug fix) Check for no line thickness before generating postscript for a
lnarr.
Deleted borderwidth and relief option from mapcanvas.  It was making it too
difficult to find the center of the window.  Now center is always found using

like the geomap::mapcanvas procedure in itkgeomap_procs, except that is does
not require [incr tk].

22 Jun 2003
Created geomap::igeomap procedure in tclgeomap_procs.  This procedure is
like the geomap::igeomap procedure in itkgeomap_procs, except that is does
not require [incr tk].

Changed rotation option so that cget::rotation returns a double value.
Adjusted map labels accordingly.
Added Postscript menu to igeomap.

25 Jun 2003

Added util directory with shape.tcl and awips_tkgm.tcl.
Added code for shptobin.
Added interstate highways to ptiger.

1 Jul 2003

(bug fix) Ensured color button path names are always lower case.

************ Changes from 2.1.2 to 2.1.3 ************

4 Sep 2003
igeomap Colors menu Save button puts color values on a line that starts with
"Colors" followed by a dump of the colorval array.

************ Changes from 2.1.3 to 2.1.4 ************

9 Sep 2003
(bug fix) Added refpoint variable to mapcanvas cget procedure.

(bug fix) Check for lineColor == None before reconfiguring.

************ Changes from 2.1.6 to 2.1.7 ************

(potential incompatibility) Dash option uses conventional X definition with
-dashes and -linestyle options instead of pillaging Tk code.

************ Changes from 2.1.7 to 2.1.8 ************

Beautified the color selection dialog.

************ Changes from 2.1.8 to 2.1.9 ************

Improved graphics context management for geomap_places.

11 Feb 2004
Changed configure and build to comply with Tcl Extension Architecture.

13 Feb 2004
Replaced libdir/$package with pkglibdir as destination for package libraries
in mkIndex.tcl and Makefile.  pkglibdir is now determined by configure instead
of Makefile.  This makes it possible to add a version suffix to the package
library.
Added PACKAGE_CFLAGS to compile macro.
(bug fix)(?) Replaced bindir with libdir in RANLIB line for static library
installation.  Libraries go into lib, not bin.
Changed installation order so that package independent libraries are copied
into package library directory before index is made.

14 Feb 2004
Changed mkIndex.tcl so that index applies only to tclgeomap package instead of
all packages in library directory.
Reversed search order for Tcl application so that configure looks for the most
recent version.

17 Feb 2004
configure.in looks for tclsh with version number taken from tclConfig.sh.

18 Feb 2004
Removed install_hdr.sh, not used by configure for Tcl Extension Architecture.
Separated build trees for tclgeomap and tkgeomap.
Added a make variable and macro to use it because FreeBSD make apparently does not do double substitutions.

23 Feb 2004
(bug fix) Moved memory free blocks in linearray commmand.
Changed file descriptor to long to match size of ClientData *.  This
undesirable cludge prevents bugs on 64 bit machines.

************ Changes from 2.4 to 2.5 ************

24 Mar 2004
Added a script to the configure process that runs tclsh and searches the
auto_path directories for tclConfig.sh.
Added TCL_INCLUDE_SPEC substitution to configuration.
Added some more directories to search for tcl.h.
(Potential incompatibility) Eliminated superfluous structure member access
interfaces.

26 Mar 2004
In configure, forced re-evaluation of compiler variables with a call to
SC_CONFIG_CFLAGS.  This is because tclConfig.sh sometimes sets variables to
values specific to Tcl instead of for the extension (specifically
SHARED_LIB_SUFFIX on FreeBSD).  Also replaced assignment to LIBOBJS with call
to AC_LIBOBJ in response to a warning from auto_conf.
Modified header installation.  Now header files are placed in pkgincludedir
and soft linked to includedir.  Thus for a default installation, the
header files will go to /usr/local/include/tclgeomap2.5, with soft links in
/usr/local/include.
Added some search paths to configure.

27 Mar 2004
Removed header file soft links from installation.  The header files go to
/usr/local/include/tclgeomap2.5.  That's it.

28 Mar 2004
Replaced call to SC_CONFIG_CFLAGS with a code excerpt in configure.in that just
sets SHARED_LIB_SUFFIX and SHLIB_SUFFIX.

31 Mar 2004
Changed search order for some directories so configure searches private
directories first.
Rearranged configure to use TCL_PREFIX from tclConfig.sh in absence of --prefix
option.

************ Changes from 2.5 to 2.5.1 ************

Version number changed to keep synchronized with tkgeomap release.

************ Changes from 2.5.1 to 2.5.2 ************

Version number changed to keep synchronized with tkgeomap release.

************ Changes from 2.5.4 to 2.5.5 ************

Made it easier to bypass Tcl allocator.

************ Changes from 2.5.5 to 2.5.6 ************

Cleaned up code that makes it easier to bypass Tcl allocator.

************ Changes from 2.5.6 to 2.6 ************

Replaced GPL with Open Software License.
Changed contact email to user0@tkgeomap.org.
Removed standard allocators.  Geography now uses Tcl allocators exclusively.

************ Changes from 2.6 to 2.6.1 ************

Changed version number to stay synchronized with tkgeomap release.

************ Changes from 2.6.1 to 2.6.2 ************

Changed to Haversine distance calculation algorithm.

************ Changes from 2.6.2 to 2.7 ************

Added GeoTime interface and geomap::time command.

************ Changes from 2.10 to 2.10.1 ************

Bug fix.

************ Changes from 2.10.1 to 2.10.2 ************

Updated build with Tcl Extension Architecture 3.2.

************ Changes from 2.10.2 to 2.11 ************

Changed version number to remain synchronized with tkgeomap release.

************ Changes from 2.11 to 2.11.1 ************

Changed version number to remain synchronized with tkgeomap release.

************ Changes from 2.11.1 to 2.11.2 ************

Changed seconds member of GeoTime_Jul to double.
(Potential incompatibility) Changed signature GeoTime_JulToCal so that it puts
the calendar time into an argument instead of sending it as a return value.
This is because fractional seconds were being truncated when the return value
was copied.  Mysterious.
This occured on
Linux topataua 2.6.12-gentoo-r4 #1 Wed Jul 13 23:22:06 GMT 2005 x86_64 AMD Athlon(tm) 64 Processor 3200+ AuthenticAMD GNU/Linux
with
gcc (GCC) 3.4.6 (Gentoo 3.4.6-r1, ssp-3.4.5-1.0, pie-8.7.9)

CORRECTION.  GeoTime_JulToCal has the same signature.  Unable to reproduce the
mysterious bug.  Seconds are still stored as doubles, although the bug was
appearing with double seconds yesterday (2007/04/19).

************ Changes from 2.11.2 to 2.11.3 ************

(bug fix) Fixed some memory leaks.

************ Changes from 2.11.3 to 2.11.4 ************

Added rotation member to projection structure.  This supercedes the separate
rotation structure, which is now deprecated.
(Potential incompatibility) Removed separate Rotation structure.  Rotations
are now part of a projection.  In tclgeomap, rotation is set with a subcommand
to the projection command.
(Bug fix) Made rotation angle follow geography convention instead of
trigonometric.
(Bug fix) When rotating a point, compute coordinates first, then assign them
back to the point.
Added Tclgeomap_LnArrToMap function.  It converts geoline arrays to mapline
arrays and saves the mapline array in a table for reuse.

************ Changes from 2.11.4 to 2.11.5 ************

Incremented version to synchronize with tkgeomap release.
