Hi! I have some random questions about the Cairo binding supported by Athens. - the rendering is done by the graphic card isnât it? - Once rendered, is the produced bitmap copied by the CPU in Pharo? With Roassal3d, we are facing a problem of performance because there is an unnecessary copy between the graphic card and the Form displayed by Pharo. I guess we have the same problem with Cairo. - Is there an example of clipping in Cairo? - Any idea how efficient the clipping is? I mean, will I gain a lot by not displaying elements located outside the visual part or should I leave the clipping do the job?
