I recently began to work on the square root implementation in MatML and I'm near to submit a patch. But as I'm new to WebKit development, I have a beginner question:
To draw the square root, the GraphicsContext::drawLine method is called but it is written (in comments) to use it only for borders. Moreover this method enforces to turn antialiasing off. I have two possibilities: - modify that method to allow (optional) antialising - use other methods. It should be better but I don't know which one is adapted. Ideally, a polyline method should be great. Is there such a method? Probably yes, as SVG & Canvas need advanced drawing. Any help is welcome!
