Support deswizzle of sparse tiled textures and some frame buffer fixes (#275)

Browse source 
* Attempt to support deswizzle of sparse tiled textures

* Use correct frame buffer and viewport sizes, started to clean up the copy engine

* Correct texture width alignment

* Use Scale/Translate registers to calculate viewport rect

* Allow texture copy between frame buffers
