- - Figure out if we need the batch/commit scheme and what to do

-   copy from back to front and reporting damage.  "copy" did this

-   The race condition happens when a client copies new content into

-   client) that only pulls in part of the repainted area.  It's only a
-   one-frame glitch, as the client will submit the damage and the
