assertion failures in SampleApp when scaled

Reported by, Dec 11 2013

Issue description

Reported via email by reed:

Try this experiment:

1. sync to latest skia
2. launch SampleApp
3. hit UP-ARROW once to introduce a slight scale in the canvas
4. hit 'a' to start animating through the slides

I am seeing multiple asserts when I run in this mode. I think this is very scary, since running with some amount of scaling is the common behavior on Android and other non-default-DPI devices (i.e. pixel).

We need to fix these!

I will work to rev gm/dm to explicitly exercise this, but as I already think we will hit asserts, we may need to fix the current problems before we can enable this on the bots...

I just ran through a bunch of them, and it crashed here:

../../src/effects/SkMagnifierImageFilter.cpp:295: failed assertion "fSrcRect.width() < src.width()"

This may be related to  issue 781 .

If we skip the ImageFilterFuzzView, there may be more; not sure yet.

When I disabled that test, I saw no other asserts. Once we fix this, we can add a bot to regularly test.

SampleApp is long gone, and I don't see this assertion in Viewer (the assert was removed a while back). I do see other asserts when I run in "s" mode with --match ImageFilterFuzzer (to repeatedly redraw the fuzzer), but let's open new bugs for those.
