Make a clean break heading for GLES compatibility. Add GLSL directory to QF and use it for all gsls based code (instead of GL). defines.h, types.h and funcs.h are derived from gl2.h from khronos. Text drawing now uses triangles instead of quads.

Add texture sub-image management. The planned uses are lightmaps and 2d icons.

typedef struct scrap_s scrap_t;
typedef struct subpic_s {
Allow clearing of a scrap. This "frees" all rectangles and subpics allocated from a scrap. subpics are owned by the scrap from which they are allocated.

Clean up global symbols for the glsl renderer. Where possible, symbols have been made static, prefixed with glsl_/GLSL_ or moved into the code shared by all renderers. This will make doing plugins easier but done now for link testing. The moving was done via the gl commit.

int GLSL_LoadQuakeTexture (const char *identifier, int width, int height,

Load bsp model textures as repeating mipmaps.

Do a pure/const/noreturn/format attribute pass. I always wanted these, but as gcc now provides warnings for functions that could do with such attributes, finding all the functions is much easier.

Call glTexSubImage2D only once per frame. Instead of once per surface... ouch. Gives about 20% speed boost on demo1 (154.7->185.7)
