I've merged my mouse theme code from the multi_device branch into the xfce4-settings code. I think it's much cleaner and in some ways better looking (fully transparent, real theme name nicer preview, better xorg integration), then the existing code. Also made a patch for xfconf to uses g_file_set_contents for better error reporting and it also run xrdb for cursor theme changes (cursor theme changes were only written on xft changes). The patch also fixes a bunch of signed/unsigned and some other compiler warnings.

Created attachment 1715 xfconf-xrbd-fix-and-compiler-warnings
The libxfconf/xfconfd parts of xfconf-xrbd-fix-and-compiler-warnings look ok to me (feel free to commit); xfsettingsd is Stephan's, so he should have a look at that particular patch band. The mouse dialog is Stephan's too, so up to him.
Both patches committed. (rev 27186 and 27185)
