libmythui: Fix a redraw bug in MythUIType
While evaluating the ATI Catalyst 'TearFree Desktop' option I noticed
that sometimes a keypress was apparently being held up until the time
on the main menu was updated.  Initially I thought that this was a lirc
or fglrx issue, but on investigation it turned out that MythMainWindow::animate
was requesting updates for empty repaint regions.  Delving further
showed that MythUIType::Draw was resetting m_DirtyRegion to empty
even if the clipRect was smaller, thus leaving unpainted regions.

m_DirtyRegion may be extended by HandleMovementPulse, SetRedraw
or SetChildNeedsRedraw etc AFTER GetDirtyArea is called.
So when MythUIType::Draw is called, clipRect may not include the whole
of m_DirtyRegion.

This patch subtracts the Draw clipRect from m_DirtyRegion instead of
simply emtying it.

Fixes #10695
