Avoid layout/full-repaint on view height change if possible

Previously we always layout/full-repaint of the whole view when the height
of the RenderView changes. In many cases this is unnecessary. Especially,
this causes unnecessary cost on Android when the top control shows or
hides.

Avoid repaint if the RenderView doesn't needs full layout.
