V44 and below might have failed on a low-memory situation. In this case, layer cliprects, especially user clip rects might have been un-installed and incorrect. This has been fixed in V45.

As a side-condition, LockLayers() removes all user- and damage-list constraints of the layer such that it will become draw-able in its full rectangle. Whether this side condition is desired or not is argueable, but we leave it like this for now for backwards compatibility. The cliprect layout LockLayers() results in is sub-optimal, but correct. UnlockLayers() restores the original cliprect layout.
