Can't zoom in after a maximum zoom out
STR: 1) load test case image 2) pinch to zoom all the way out (shrinking image) 3) try to zoom out result: image doesn't zoom out

Summary: Can't zoom out after a maximum zoom in → Can't zoom in after a maximum zoom out
I can reproduce this if in step 3 I try to zoom in by pinching near the center of the screen. If I pinch in the top-left quadrant of the screen I do get a response (although it's kind of jumpy). Turning on layer borders shows that the purple border (which is what our hit tests use) shrinks upon zooming out and so the hit tests starts failing unless you pinch specifically inside that area. Although I think fixing bug 732971 might make this bug less obvious, this is a legitimate bug and should be addressed separately.
Component: Pan and Zoom → Panning and Zooming
Product: Firefox for Metro → Core
For my own future reference, I think the problem here is that the untransforms in APZCTreeManager to find the right APZC is not working as I expected. If an async transform is in effect on a layer (such as after zooming out on the image above) but there are parts of the layer that extend beyond the originally-visible rect (the purple border) then the hit test should match on those parts as well.
Not able to reproduce this anymore.

I can still repro this (with some help from turning on layer borders), but bug 932525 might take care of it.

I suspect this one is fixed by bug 932525 although I can't test it right now because my local build has a bunch of other patches applied that will interfere with this. Botond, could you verify to see if this is fixed?

Botond, could you verify to see if this is fixed? Looks like it's fixed.
