lazy programmer and I found that the easiest way to keep buffer handling
at peak performance ;-).
+ Q) I'm getting a "bad font!" fatal error.
+ A) By default, DOS GLUT compiles with GLUT_IMPORT_LIB, to cope with variable
+ access inside dynamic modules (same mechanism used for Win32 _DLL). Since
+ -DGLUT_IMPORT_LIB affects Mesa's `glut.h', your apps must be compiled the
+ same way GLUT was compiled (either with or without defining it). If you
+ want to use another `glut.h' when building your own demos, or just don't
+ feel happy about this, make sure you remove the line with GLUT_IMPORT_LIB
+ from `Mesa/src/glut/dos/Makefile.DJ' before (re)making GLUT. Beware, this
+ means you will never EVER be able to safely use `glut.dxe'!
+
Q) How do I query for a list of available video modes to choose as a visual?
A) This is an ugly hack, for which I'm sure I'll burn in hell.
First, query for a list of modes:
