Cache surface textures on the GPU to eliminate duplicate uploads.
At the moment GLRenderer is unconditionally uploading a new copy of every
visible surface to the GPU, on every frame. This branch changes that to
only upload textures for visible surfaces when they change.
In a realistic GUI with multiple surfaces where most of them don't change
on every frame, this eliminates most of the texture copies. So performance
with multiple visible surfaces should be greatly increased.
Also resolves bug: LP: #1263592. Fixes: https://bugs.launchpad.net/bugs/1263592.
