Subject: [PATCH 30/38] XWayland: Don't commit empty surfaces

Instead of attaching, damaging and then committing a new buffer as soon
as we allocate a pixmap, just attach and damage the entire buffer.  When
the buffer is changed, we'll commit the changes.

This avoids an ugly black (on SHM) flash when a window is mapped or
resized.
