Bugzilla #4226: Change the pixmap migration strategy for the CopyNtoN case.

Browse Source 
Now, if either source or dest were in framebuffer, try to get both
    there, but prefer system memory for both otherwise. Required making
    exaasync.c go through the try-acceleration path. This significantly
    improves window resizing under composite, because previously the
    pattern of creating a new pixmap and copying default contents from the
    screen caused a fallback every time due to the new destination pixmap
    being in system memory.
