solvespace/ui.h
Jonathan Westhues c4b442f92f Initial work to move text window guts into platform-independent
code. This is now drawn using gl, and the bitmap font (both there
and in the graphics window) is drawn from a texture from a static
table, not from the Win32 functions, since that's ~1000x faster.

So this adds a tool to generate that table. With luck that will
also fix my font issues under WINE, which won't have to render the
TTF itself.

Still needs some cleanup, and to make all the cosmetic improvements
that I want.
