This has two side effects: - The number of overlay planes is reduced from 24 to 8. This is temporary and will be increased again in the next patch. - The ID of the various planes is changed again, and we will now have all the primary planes, then all the overlay planes and finally the cursor planes. This shouldn't cause any issue since the ordering between primary, overlay and cursor planes is preserved.
