Adventures in virtual texture space, part 14

This is just an update to show my progress.

Texture coordinates are now generated correctly, and popping of pages is extremely rare now and basically only happens if you travel trough a wall.

Note that I haven't put the texture compression code in yet, so IO performance will actually get better in the future.

Also, the frame rate in the video is rather chaotic, this is due to the screen recorder competing with the application for resources.
