It's managed automatically - OpenGL/D3D virtualise VRAM for you, so that
the only thing an app developer (or Quesa) needs to do is to activate
the required texture before drawing.

If activating that means bumping other textures out of VRAM, they use
whatever scheme they see fit (typically LRU) to make space.
