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.
