compositor: don't recalculate shape and masks until surface arrives

Browse Source 
mutter uses the windows "buffer rect" to determine how big to draw the
titlebar, and what masks to apply to the window for opaque areas.

That buffer rect is updated the moment we initiate a resize operation on
a window, but not actually accurate until the resize operation finishes

This commit makes sure the window actor keeps using its old shapes and
masks until any pending resize operation finishes.
