This is the result of yesterday's IRC discussion. Modifying the TiledBackingStore to test each tile rect back to the visible/cover area wouldn't scale as well since we would have to test each single tile each iteration. I found out that clampedBoundsOfProjectedQuad is exactly what I was needing so I'm using it instead here.

Any reason why you don't just merge this into 74720?

This patch got merged pushed with the content of bug #74720. Got it split since this changes the behavior while the rest was just moving code around, but the other patch was huge already anyway.
