Permaorange, but filing so I have something to star until resolved.

What I know so far:
* The last native Android M1 green was , which is 20 hours ago.
* Bug 767064 landed (, turning M1 orange (
* Bug 767064 was backed out by RyanVM in
* However M1 is still orange, this time with another error:
* My first thought was that something else landed after bug 767064 which had broken things further, but bug 767064 didn't cause a [aborts the suite] type failure and yet the new failure doesn't appear in the logs right until the backout.
* I've tried clobbering, but that didn't help:
The backout diff also seems to match the landing exactly, so doesn't appear to be a problem with the backout.
Regression range:

(and keep on pressing the downarrow until you see the first green)

Bug 728524 has been backed out in, so we shall find out soon enough if that was what caused this :-)
I've build fennec locally and don't see that error on Asus Transformer Prime device.
Clicked on "textures" run
Make sure you are running in the mochitest harness (TEST_PATH=content/canvas/webgl make mochitest-remote) as that could yield different results.  I was able to reproduce this 100% of the time.  After spending 2 hours trying to narrow the test case down with no luck, I caved into the 'lets back this out' mindset.  

If the test cases are not easy to figure out, others will not be able to aid in debugging them.

This was a failure in 4 files:

There will inevitably be some false positives; for that (and the bugspam) I apologise. Filter on orangewfm.
