* Fixes hardware bitmap capture * Fixes mutable bitmap capture (no flickering) * Adds basic single-frame LRU cache to avoid repeated readbacks of GPU resources * Does up-front readback of GPU resources * Moves serialization off RenderThread again thanks to up-front readback avoiding needing GPU access off-thread * Reduces RAM usage & improves performance by serializing directly to output stream instead of first copying to a byte[] Bug: 174223722 Test: PictureCaptureDemo mirrors the content Change-Id: If7ec208b61d5b917e82087cc312880fc5a38c943
