** In FrameLayerBuilder, the The back ThebesLayer previously contained content that couldn't be optimized to a ColorLayer, and once it can be, it decide to keep using the ThebesLayer since it's already allocated. So the improper thebeslayer will make the camera previewing be composited by HwcComposer2D. | ** In FrameLayerBuilder, the The back ThebesLayer previously contained content that couldn't be optimized to a ColorLayer, and once it can be, it decide to keep using the ThebesLayer since it's already allocated.

** In KK, the class BufferItem is migrated from BufferQueue to IGraphicsBufferConsumer, which leads to BufferItem manipulating functions(acquireBuffer, queueBuffer, dequeueBuffer...etc) have to be modified carefully. Meanwhile, due to gonk's custumization also add some data member to carry gecko specific data, the relative refactoring need to consult with Sotaro in advance. | ** In KK, the class BufferItem is migrated from BufferQueue to IGraphicsBufferConsumer, which leads to BufferItem manipulating functions(acquireBuffer, queueBuffer, dequeueBuffer...etc) have to be modified carefully.
