Thanks Kenneth, Martin has promised to look at this tomorrow but if he doesn't I'll land.

Comment on attachment 180857 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=180857&action=review Looks good to me, with a couple small suggestions. > Source/WebCore/platform/graphics/texmap/TextureMapperGL.cpp:448 > + const GC3Dfloat Left = 0; > + const GC3Dfloat Top = 0; > + const GC3Dfloat Right = 1; > + const GC3Dfloat Bottom = 1; > + const GC3Dfloat Center = 0.5; Style nit: Left should be left and so on. > Source/WebCore/platform/graphics/texmap/TextureMapperGL.cpp:449 > +#define SIDE_TRIANGLE_DATA(x1, y1, x2, y2) x1, y1, x1, y1, x2, y2, x2, y2, Center, Center, (x1 + x2) / 2, (y1 + y2) / 2 I think a comment here explaining that each point is followed by a control point would make this a lot clearer. > Source/WebCore/platform/graphics/texmap/TextureMapperShaderManager.cpp:168 > + position = center + (position - center) * inflationRatio; So center + (position - center) here ensures that the center point is never expanded? Nice.
