+ GraphicsContext: low quality drawImage and drawImageBuffer should use InterpolationLow
+ https://bugs.webkit.org/show_bug.cgi?id=49002
+
+ Reviewed by Chris Dumez.
+
+ When using low quality image scaling for images which are getting painted often,
+ the code used InterpolationNone, which make the images look even worse than they should.
+
+ Not easily testable.
+
+ * platform/graphics/GraphicsContext.cpp:
+ (WebCore::GraphicsContext::drawImage):
+ (WebCore::GraphicsContext::drawImageBuffer):
+ (WebCore::GraphicsContext::drawConsumingImageBuffer):
