Subject: Force repaint of modal sheet in Cocoa.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

With the raster engine on Mac OS X, modal sheets
only get their content painted once the sliding
down animation is over.
By forcing the repaint, the modal sheet has the
correct painting during the whole animation.
