bug:8037003 A recursive drawDisplayList call is now entirely deferred before playing back to the screen and issuing GL commands. This way, the entire stream can be inspected, optimized, and batch work (such as uploading textures) before issuing commands. Additionally, this fixes an issue where operations draw could move across restores corresponding to saveLayer(alpha). Those and other similar cases (such as complex clipping, requiring the stencil) are now treated as batching barriers, with the operations that change renderer state in a way that's difficult to defer are just re-issued at flush time.
