Fix non-anti-aliased frame update.

Fix non-anti-aliased frame update.

m_contentsCangeCommitted (now renamed to m_contentsChangeResolved) was
not getting set on non-anti-aliased DrawingBuffers, causing us to always
skip setting m_animationFrameInProgress to true. This in turn skips
calling glReadPixels() for CPU-composited frames.
