Well, the plan is to not do anything yet :-). If you feel that you can contribute time and effort, please go right ahead and check in whatever changes you find time to do. The areas in most need of work is font selection, that is not handeled correctly. The way Emacs faces specify fonts and how they map to X fonts needs to be handeled in a way that is appropriate for antialiased fonts as well. Currently Emacs faces specify slant, size and such and then translate to/from XLFD (the -courier-normal-*-12-*-*- notation). This is not appropriate for antialiased fonts. The calculation of the size of the frame (lines => pixels) does not seem to be correct either, I suspect the calculation uses the wrong font. People has reported various redrawing problems also. And then there is the whole i18n problem. Specifically, Xft wants unicode characters, but Emacs has its own internal (Mule) representation. I think we must integrate XFT and Unicode before this can be sorted out correctly. Jan D.
