700755 - Add RGBA32 support to gfxImageSurface

Status: NEW

(Core :: Graphics, defect)

Description

[James Willcox (:snorp) ([e-mail]) (he/him)]

Fennec on Android draws Flash content to a gfxImageSurface. In transparent mode, Flash wants to use RGBA32, which gfxImageSurface does not support. Additionally, there is also a canvas API we have to implement for Flash and we need RGBA32 there as well (see ANPCanvas.cpp and friends).

For clarification, does Flash need RGBA32 to (or not to) be alpha-premultiplied?

It isn't specified (shocking, I know), but I guess I'd expect it to not be premultiplied.
