So, we are (still) limited to Matrox cards and (aprtially) NVIDIA?

Yes, I silently folow your discusion on <render> list... And that's why I have asked wether there is an overlap with libart I think it would be interesting to have integrated in X extensions some parts of libart .

It's not very well known but widely used. GhostScript uses it foir PostScript/EPS rendering, incl. font anti-aliasing. It's also used by SodiPodi (http://sodipodi.sourceforge.net) - vector drawing program for GNOME, and in Karbon14 (vector-drawing program for KDE3). Besides, it's used in Mozilla's SVG module (check [1], [2]). [1] http://www.mozilla.org/projects/svg/ [2] http://www.croczilla.com/svg/ IIRC KSVG (KDE's native SVG implementtaion) uses libart, too. | | Keith Packard XFree86 Core Team HP Cambridge Research Lab | _______________________________________________ | Render mailing list | [EMAIL PROTECTED] | http://XFree86.Org/mailman/listinfo/render -- Vadim Plessky http://kde2.newmail.ru (English) 33 Window Decorations and 6 Widget Styles for KDE http://kde2.newmail.ru/kde_themes.html KDE mini-Themes http://kde2.newmail.ru/themes/ _______________________________________________ Render mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/render
