* Prior to validateDisplay, a layer may be marked as Composition.CURSOR.
* If validation succeeds (i.e., the device does not request a composition
* change for that layer), then once a buffer has been set for the layer
* and it has been presented, its position may be set by this function at
* any time between presentDisplay and any subsequent validateDisplay
* calls for this display.

* Once validateDisplay is called, this function must not be called again

*
* May be called from any thread so long as it is not interleaved with the
* validate/present sequence as described above.
* The position of a cursor layer can be updated without a validate/present display
* sequence if that layer was marked as Composition.CURSOR and validation previously succeeded
* (i.e., the device didn't request a composition).
