Taras noticed the following site causes severe multi-second janks:

I grabbed a quick profile and found us spending 5.3 seconds in mozilla::gfx::DrawTargetD2d::SetupEffectForRadialGradient on my fast machine with a GTX 570. The page is smooth in Chrome. The page does not jank with hardware acceleration disabled.

This behavior occurs both on Nightly & Release, so it's not a regression
Summary: Gradients causing multi-second pauses on a page → Gradients causing pauses of multiple seconds
We should add a way to bail from conditions like this. This page made it impossible to close the tab on my laptop

I think we should just fix bug 823147 which makes this needlessly slow with D2D
Depends on: 823147
