Ok that was not that trivial to handle AntiAliased Quadratic Curve primitive on the GPU without tesselation ( I thought the Curve primitive is harder to implent than the Fill Path ).
But I did it ;)
You can see some test who expose some different join and Caps for each curve with differents stroke size.
I also used previous line and Ellipse Primitive to display curves handles :)
You can’t see it with the image but roses are animated and thanks to the AntiAliasing all is super smooth and eye pleasing.
