annotate src/video/win32/SDL_gapirender_c.h @ 4525:3abf0b9cafad

pelya 2010-07-12 03:53:48 PDT In function GLES_RenderCopy() in SDL_renderer_gles.c:819 there is one memcpy() that can be avoided if we're updating whole texture. Because of that the SDL 1.3 in compatibility mode is working even slower than software rendering in SDL 1.2.
