Changes from version 1.7 to 2

POTENTIAL INCOMPATIBILITIES:

All of the C library functions are now in two packages: tclgeomap and tkgeomap.
All of the Tcl library procedures are now in the tclgeomap_procs and
tkgeomap_procs packages.

tclgeomap and tkgeomap 2.0 only work with tcl/tk 8.3 or later.

geomap widgets and geomap canvas items are GONE.  They have been superceded by
geomap_lnarr and geomap_place canvas items.

All commands have been moved into the "geomap" namespace.  Note especially the
new names for the geolinearray, geoplace, and geoproj commands.
georadius -> ::geomap::georadius
latlonok -> ::geomap::latlonok
mapptok -> ::geomap::mapptok
lonbtwn -> ::geomap::lonbtwn
gclcross -> ::geomap::gclcross
rotatpt -> ::geomap::rotatpt
scalept -> ::geomap::scalept
domnlonpt -> ::geomap::domnlonpt
domnlat -> ::geomap::domnlat
domnlon -> ::geomap::domnlon
gwchpt -> ::geomap::gwchpt
gwchlon -> ::geomap::gwchlon
dmstodec -> ::geomap::dmstodec
dectodm -> ::geomap::dectodm
dectodms -> ::geomap::dectodms
cartg -> ::geomap::cartg
geolinearray -> ::geomap::lnarr
geoplace -> ::geomap::place
geoproj -> ::geomap::projection

The geomap::lnarr (formerly geolinearray) command has the following subcommands:
fmxdr, fmbin, fmascii, fmlist.  The other subcommands (toxdr, tobin,
toascii, tolist, info, descr, limits, and containpt) belong to the individual
commands created for each new linearray.

'geolinearray rm ...' and 'geoplace rm ...' are gone.  Linearrays and places
are deleted by deleting the corresponding linearray and place commands.
This is usually done by renaming the linearray or place command to "" with the
tcl rename command or by deleting its parent namespace.  Linearrays and places
disappear from all displays when their commands are deleted.

'geomap::place list' and 'geomap::lnarr list' are gone.

'geomap::place nearest' and 'geomap::place inrange' require list of place names
to search.  All geomap::place and geomap::lnarr commands assume place and
linearray names are global or fully qualified.

The 'geolinearray geomaplist' command is gone.  Arrays on display in a canvas
should be given a common tag.  Then they can be selected with the canvas
'find withtag' command.

Cardinal directions (such as for geomap::place step) should be spelled out or
given as unambiguous abbreviations.

'geoproj copy' command is gone.

Bitmaps drawn at items no longer take a background color.  Background is
transparent.

geomap_lnarr items do not display bitmaps.

geomap_lnarr items specify dashes with -dash and -dashoffset options instead of
-style.

Source code for Tcl and Tk packages conforms to Tcl/Tk Engineering Manual.
