Bug Description

This is a rendering improvement made possible through the removal of the software renderer.

Most functionality in image_transformations can be done quicker with OpenGL. Right now the strategy there is to do an image transformation once and cache it. With opengl doing it on every frame is quick and more memory efficient.

There is also a method that resizes a surface that uses sdlgfx. This functionality could be rolled into the blit call and we could get rid of this dependency with a speedup.

image_transformations and the dependency on sdlgfx is gone and most stuff is now done in OpenGL on render instead of cached. I think this has no action items anymore.
