In memory of Paul Alexi The attached patch is a rework of outline emboldening.
1) It introduces uneven emboldening in x- and y-direction. I understand that the straight change in API is not going to fly but I really do not want to introduce a separate function for that. We can do va_arg here, i.e., we do even or uneven emboldening depending on whether one or two strength arguments passed. Would this be acceptable and backwards compatible? 2) It removes a bunch of trigonometry to speed things up. Instead of calling Atan2's and Cos, we rotate by 90 degrees and cleverly weigh the incoming and outgoing vectors to figure out the shift direction. The only complicated operation per each point is FT_Vector_Length. I would appreciate any feedback. Alexei
