Previously, we weren't scheduling a visual update when our surface was created, so we'd just continue to show black until the author requested a new animation frame. After this CL, we schedule a visual update as soon as our surface is created. As part of this change, I've removed knowledge of the GPU delegate from PlatformView. Now, all the calls from PlatformView to the GPU system bounce through the UI delegate, which serializes the commands with other commands from the UI engine to the GPU rasterizer.
