--- Comment #3 from Fujii Hironori <Hironori.Fujii at sony.com> ---
FilterEffect::transformResultColorSpace does nothing if USE(CG). It calls ImageBuffer::transformColorSpace otherwise.
https://github.com/WebKit/WebKit/blob/3de6f842827f19bb0b6de1068d88026e8868cf26/Source/WebCore/platform/graphics/filters/FilterEffect.cpp#L641

There are three problems.

1. ImageBuffer::colorSpace() returns the old color space even after ImageBuffer::transformColorSpace.
2. ImageBufferBackend::colorSpace() returns the old color space even after ImageBuffer::transformColorSpace.
3. convertImagePixels doesn't support color space conversion yet for USE(ACCELERATE) && USE(CG).
