-//////////////////////////////////// hey. you can do some config here. either preload glyphs or re-read font file each time.
-//comment out the next line if you want what is probably the slow version. might be safer and use less memory though.
-//maybe just put the font file in ram. linux caches that crap anyway, right?
-//testing showed preloading was at least 10x faster.
-#define PRELOAD_GLYPHS
-//only 8-bit characters atm.
-//and we'll need to malloc the amount of lines each character will have.
-//and malloc each line in that glyph...
-//or just set it statically.
