OpenGL does those sorts of things very well, accelerated, on all major
OS's... so long as you have a video card from the past 3 or 4 years,
and so long as you have drivers for it.
I found out how to convert SDL_Surfaces to OpenGL textures in a NeHe
demo (should be linked of the SDL page). Beyond that I have no
knowledge of how to get your data into OpenGL textures.
