WebGL conformance test fails when alpha=128

Project Member Reported by xidac...@chromium.org, Mar 15 2016

Issue description

Please refer to here for more details:

https://github.com/KhronosGroup/WebGL/pull/1527

In particular, the tex(Sub)Image2D fails when the input is ImageData and the alpha channel is 128.

This also happens in createImageBitmap() from an image whose alpha channel is 128 (possibly some value that is not 255).

I am not reverting the roll because my understanding from this bug is that this was failing before.
