REGRESSION (r202927): The internal size of the ImageBuffer is scaled twice by the context scaleFactor https://bugs.webkit.org/show_bug.cgi?id=159981 <rdar://problem/27429465> Reviewed by Myles Maxfield. Source/WebCore: The change to propagate color spaces through ImageBuffers created an alternate version of createCompatibleBuffer. This version accidentally attempted to take the display resolution (i.e. hidpi) into account when creating the buffer, which meant it was being applied twice. The fix is simply to remove that logic. The caller of the method will take the resolution into account, the same way they did with the old createCompatibleBuffer method. Test: fast/hidpi/pdf-image-scaled.html * platform/graphics/cg/ImageBufferCG.cpp: (WebCore::ImageBuffer::createCompatibleBuffer): Don't calculate a resolution - just use the value of 1.0. LayoutTests: * fast/hidpi/pdf-image-scaled-expected.html: Added. * fast/hidpi/pdf-image-scaled.html: Added. * fast/hidpi/resources/circle.pdf: Added.
