GL generally really doesn't like BGRA, and it's not as important as it was in the D3D9 days.
As I understand it, our main blocker here is mostly getting RGBA out of the decoders instead of BGRA, which seems actionable.
Using RGBA instead of BGRA cure a lot of ongoing pains in handling GL and GLES's spotty and poor BGRA support.

WebRender still have to support both, it's more of a question which one to prefer.
The work has been going in 1548339 to address this.

Can you elaborate on why both need to be supported?
For example, WebGL uses only RGBA.

Consulted with :jrmuizel once more, we have currently two sources of BGRA data: Skia and ImageLib. The latter can be fixed, at least :aosmond have a plan to do so. It's not entirely clear if the former is easy to fix.
