Eliminate unclipped CLEAR from meta-surface playback

Browse source 
The optimization that avoids replaying commands prior to an unclipped
CLEAR operation now starts playback from the first command after the
CLEAR. This avoids the need to handle the unclipped CLEAR in the PDF
surface.
(cherry picked from commit 875e32178e)
