Today I noticed a fairly tragic bug in ploticus 2.30.. when using

pl -gif ... -csmap ...
pl -png ... -csmap ...
pl -gif ... -map ...
pl -png ... -map ...

NO MAP OUTPUT is produced!!!! This occurs on all platforms when creating
GIF/PNG/JPEG images, regardless of whether -mapfile is specified or not.
Someone a while back mentioned their complete confusion in generating
image maps.. perhaps this contributed to the problem. I'm surprised
nobody has said anything.. isn't anyone generating image maps out there?

SVG is unaffected, and libploticus/Makefile_api are unaffected.

The problem is in the Makefile... -DPLOTICUS must be in effect during the
compilation of grgd.c .. The fix is to edit src/Makefile, adding
-DPLOTICUS to line ~ 288:

gd13files:
$(CC) -c grgd.c -DGD13 -DPLOTICUS -I./gd13 -o grgd13.o

.......... and to line ~ 294:

gd16files:
$(CC) -c grgd.c -DGD16 -DPLOTICUS -I./ -I./gd16 -o grgd16.o


I guess the reason this slipped thru is that my quality control suite
doesn't run an example that generates an image map.. will fix this. I do a
lot of work with image maps regularly here, but almost all of it is
generated via libploticus, not the pl command.


Appologies!
