	the portable parts of this file should be moved into RENDER.C 
Friday, August 12, 1994 7:57:00 PM
	invisible polygons and lines are never drawn.
Thursday, September 8, 1994 8:19:15 PM (Jason)
	changed behavior of landscaped lines
Monday, October 24, 1994 4:35:38 PM (Jason)
	only draw the checkpoint at the origin.
Monday, October 31, 1994 3:52:00 PM (Jason)
	draw name of map on overhead map, last.
Monday, August 28, 1995 1:44:43 PM  (Jason)
	toward portability; removed clip region from _render_overhead_map.

Feb 3, 2000 (Loren Petrich):
	Jjaro-goo color is the same as the sewage color

Feb 4, 2000 (Loren Petrich):
	Changed halt() to assert(false) for better debugging

Feb 18, 2000 (Loren Petrich):
	Made VacBobs display properly 

May 2, 2000 (Loren Petrich):
	Added XML setting of overhead-map-display parameters;
	also imported the number of paths for displaying them.
	
	Can display alien monsters, items, projectiles, and paths.

Jul 4, 2000 (Loren Petrich):
	Made XML map-display settings compatible with the map cheat.

Jul 8, 2000 (Loren Petrich):
	Added support for OpenGL rendering;
	in these routines, it's the global flag OGL_MapActive,
	which indicates whether to do so in the overhead map

Jul 16, 2000 (Loren Petrich):
	Added begin/end pairs for polygons and lines,
	so that caching of them can be more efficient (important for OpenGL)

Monday, August 28, 1995 1:41:36 PM  (Jason)

Feb 3, 2000 (Loren Petrich):
	Jjaro-goo color is the same as the sewage color

Feb 4, 2000 (Loren Petrich):
	Changed halt() to assert(false) for better debugging

Jul 8, 2000 (Loren Petrich):
	Added support for OpenGL rendering, in the form of calls to OpenGL versions

Jul 16, 2000 (Loren Petrich):
	Added begin/end pairs for polygons and lines,
	so that caching of them can be more efficient (important for OpenGL)

Aug 3, 2000 (Loren Petrich):
	All the code here has been transferred to either OverheadMapRenderer.c/h or OverheadMap_QuickDraw.c/h
[End notes for overhead_map_macintosh.c]

Nov 12, 2000 (Loren Petrich):
	Added automap reset function and XML parsing
