Bug 963073 - Merge tiling branch. r=Bas,jrmuizel,BenWa This work is mainly porting tiled layers to new textures, implementing double-buffered tiles and implementing a texture client pool, to be used by tiled content clients. Any questions regarding this patch should go to: Bas Schouten <> Chris Lord <> Nicolas Silva <> In their absence questions can be directed to: Jeff Muizelaar <> Benoit Girard <>
