Android: Add tests for VideoFrame.Buffer.toI420() and cropAndScale()

Browse Source 
This CL adds tests that are primarily targeting
VideoFrame.Buffer.toI420() and cropAndScale(), but includes the whole
chain for YuvConverter, GlRectDrawer, and VideoFrameDrawer.

It also includes a couple of fixes to bugs that were exposed by the new
tests.
