I'm working on circle alignment for OpenGL, it also requires some shader work so it's not that trivial. I'll try to merge all this by Wednesday. Answering other questions: - poor cairo graphics on OSX: do you have a Retina display? If so, what's the native resolution of the screen in your computer and what's the one reported when creating the cairo context (can you printf screenSize in CAIRO_GAL::initSurface())? I'm asking because on many OSX flavors the contents of the window are not rendered at native display resolution but half of it and then scaled 2 times if the app is not using Apple's Quartz drawing API? If screenSize <= 2x your native screen resolution, it's likely the problem causing ugly display. IIRC we had a similar issue with OpenGL canvas that someone fixed with a special patch to Mac version of wxWidgets (using some fancy Objective C call). - concerning text rendering: as JP mentioned already, it's a problem with our stroke font. It looks bad at low zooms because it lacks hinting. I doubt it's possible to add it to our stroke font renderer given the amount of time and effort it requires. Alternative solution is to use TrueType system fonts, but this surely won't happen earlier than in V6. - misaligned arcs and circles are caused by lack of rounding of circle coordinates/radii in the vertex shader. I'm working on a fix.
