When an image has a non-zero SMaskInData it means that the image has an alpha channel.
With JPX images, the colorspace isn't required (by spec) so when we don't have it, the JPX decoder will handle the conversion in RGBA format.

I think there a regression in issue11004-page1 and issue12579-page3 since they don't render anymore in the reference tests. Given that the earlier test run didn't seem to have it, it looks like the new changes changed the behavior; I've provided more information in the comment below.

With that addressed this patch also LGTM; thank you for fixing this issue!

When an image has a non-zero SMaskInData it means that the image
has an alpha channel.
With JPX images, the colorspace isn't required (by spec) so when we
don't have it, the JPX decoder will handle the conversion in RGBA
format.
