allow for a limited number of updates on transitioning windowspastdamages

Repair transitioning windows not more than ten times per second.
Only implemented in the EGL variant.

 * src/mcompositewindow.h
 * src/mtexturepixmapitem.h:
   Add an optional Time parameter to MCompositeWindow::updateWindowPixmap()
   denoting the time when the damage notification was sent by the server.
 * src/mtexturepixmapitem.h:
 * src/mtexturepixmapitem_p.cpp:
   Add MTexturePixmapPrivate::pastDamages to remember them for the timeframe
   if necessary.
 * src/mtexturepixmapitem_egl.cpp (MTexturePixmapItem::updateWindowPixmap::updateWindowPixmap):
   If we receive a damage during a transition check if we can afford a repair
   an do it if all's positive.
 * src/mtexturepixmapitem_glx.cpp (MTexturePixmapItem::updateWindowPixmap::updateWindowPixmap)
   Just added the new parameter, but left unused.
