Speaking of which, I have a small image viewer I made in SDL for use on
our set-top box connected to the TV. It uses raw SDL and SDL_image to load
and show images and works very well. Would it benefit from loading the
images into textures and using OpenGL for the display? Raw speed would
probably not be improved at all, but it could facilitate all kinds of nice
effects when switching between images: fades, rotates, zooms etc, stuff
that the normal "pixel based" images can't really achieve.
