macOS video rendering

[philn]

Can someone else with a mac please test this?

I just tested it and it works. Thank you!

OK, so we're not passing the stride info to WebRender when we create the ImageDescriptor objects, so when it's rendering our images, the (stride-width) pixels at the end of the line will appear at the start of the next line, which makes the rendering skewed. We can also use jya's upstream fix in Bug 1421187 to output i420 frames. I've pushed with these changes.

Ah nuts, I forgot to git add all of jya's upstream changes. :(
