If not, it would not make sense, to make an own module of it. As far as I know, cairo and cairo-svg are supporting the most platforms, but might still lack support for the one or other. Thus the module would be only availabe on a certain platform. As I understand at least Win32, Unices (X11), MacOS X and QNX should be supported. > same icon in two different sizes, while minimizing wasted cycles.

For a project SDL_ttf does not make use of Pango as far as I know. When I say Pango, I mean that ;-). The code is based on Pango 1.11. I think, I need to look through it in order to make it work with pygame and the latest pango release. > like OLPC there are a lot of issues with stuff like RTL languages and > Arabic scripts, both of which as painful with a simple font layout system. > Regards Marcus
