Comment on attachment 462528 [details] WIP patch View in context: https://bugs.webkit.org/attachment.cgi?id=462528&action=review > Source/WebCore/platform/graphics/texmap/TextureMapperShaderProgram.cpp:113 > + float viewportSpaceDistance = distance(centerInViewportCoordinates.xy / centerInViewportCoordinates.w, controlPointInViewportCoordinates.xy / controlPointInViewportCoordinates.w); We should avoid divisions. bug#245265 is going to solve this bug by calculating the denominator separately.
