Hi Alan, what I was pointing out is that, given the architecture we chose to adopt for graphics (i.e. Cairo), make stuff resolution independent is "free". If what you are suggesting is that we should not use Cairo because it has performance problems than I have two objections: 1 Profiling shows that the main bottleneck is not Cairo itself but the 888 -> 555 conversion. Cairo does not support 565 but that's fixable if we want to. 2 We need a powerful 2D API, given that the user experience design is heavily based on vector graphics. I don't see realistic alternatives to Cairo (and I don't think we should be looking for one given 1) Cheers, Marco _______________________________________________ Sugar mailing list [email protected] http://mailman.laptop.org/mailman/listinfo/sugar
