+ 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) What is NUL driver good for, if I don't get any output at all?
+ A) For debugging. The NUL driver is very much like OSMesa. Everything is
+ done just the same as VESA/VGA drivers, only it doesn't touch your video
+ hardware. You can query the actual buffer by issuing:
+ DMesaGetIntegerv(DMESA_GET_BUFFER_ADDR, &buffer);
+ and dump it to a file.
