[PATCH] pixmap: fix reverse optimus support with multiple heads

For doing reverese optimus to multiple outputs on a secondary GPU
the GPU can store the blits into a large screen pixmap, unfortunately
this means we need a destination offset into the dirty code, so
add a new API that just adds this interface.
