+  - When copying from pixmap to framebuffer, right now we just copy
+    the bits from the fb allocated pixmap.

+  - With hashing, we need to copy it to video memory, hash it, then set the
+    "unique" field to that hash value (plus the QXL_CACHE

   It may be beneficial to send pixmaps in smaller tiles, though Yaniv
