Add pixel density concept to the code. So, it draw about the same size on

mdpi and hdpi devices.

Update the UI assets for mdpi

Fix a issue that GLSurfaceView didn't call onPause and onResume in Camera.
Refactor. Improve the drawing and animation.

Also fix the RawTexture unsupported operation bugs and the NullPointerException
in GLRootView.
