http://hg.mozilla.org/users/bschouten_mozilla.com/tiling/summary 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 <bschouten@mozilla.com> Chris Lord <clord@mozilla.com> Nicolas Silva <nsilva@mozilla.com> In their absence questions can be directed to: Jeff Muizelaar <jmuizelaar@mozilla.com> Benoit Girard <bgirard@mozilla.com>
