Comment on attachment 653184 [details] [diff] [review] Updated patch r=dbaron, except you should also add tests for the broken things this is fixing. You really need tests for this stuff. If roc, cjones, you, etc., can't figure out a good way to test the whole thing, then you should at the very least write tests that let you test interpolation in the layers code, so that you can test all the value-specific code.

Backed out for reftest failures on Android armv7 builds: https://tbpl.mozilla.org/?tree=Mozilla-Inbound&rev=da94e7f02dad&jobname=android.*reftest remote: https://hg.mozilla.org/integration/mozilla-inbound/rev/a22d26116ebe

I couldn't get try to run these tests for some reason. This patch really shouldn't change any android code, so if it fails tests we should try a clobber. https://hg.mozilla.org/integration/mozilla-inbound/rev/9b7722e0d014

This patch is very safe and fixes a crash.
