Don't blur too many layerst13.0
An application requesting lots and lots of blurs:
a. Enables pixel stealing by measuring how long it takes to perform a
blur across windows
b. Probably isn't very valid anyways.
So, just arbitrarily pick an upper bound for blur requests that a
display is allowed to manage (10), and disable everything else.
Arbitrarily, pick the 10 "front-most" blurs to be respected.
