Bug 1446309 - Part 3. Properly handle ImgDrawResult for WebRender display list generation. r=tnikkel When generating display lists for WebRender, we were not caching the draw result via nsDisplayItemGenericImageGeometry::UpdateDrawResult (or similar) after completing CreateWebRenderCommands. This is important because reftests use this to force sync decoding for images; it may be a reason for image-related intermittent failures on *-qr builds. Additionally, we may have been requesting fallback in cases where fallback could not do anything more than WebRender could. For example, if we can't get an image container yet, there is no point in requesting fallback because it might just be we haven't started decoding yet. We should just return the actual draw result in such cases.
