Reviewed by Stephen White.

Source/WebCore:

Don't apply the color profile if the user has requested separate alpha.

Test: fast/canvas/webgl/texture-color-profile.html

* platform/image-decoders/skia/ImageDecoderSkia.cpp:
(WebCore::ImageFrame::setStatus):

LayoutTests:

Verify that the image's contents don't get destroyed if using both
separate alpha as well as the browser's colorspace conversion.
