Splotchy drawing of sub-pixel width splines in GraphicsContextCG
Compare the rendering with Skia. The Skia rendering looks better, although again, I'm not enough of a graphics expert to know which one is correct. If this is a CG bug and needs to be filed in radar instead, I'm happy to do that. Given that this may be simply related to how we (WebKit) calls CG, I'm starting here.
