10695	[PATCH] libmythui: Fix a redraw bug in MythUIType	Lawrence Rust <lvr@…>	stuartm	"While evaluating the ATI Catalyst driver '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.
