sort source files into these directories according to which part of the WM
2007-12-19 Havoc Pennington <hp@redhat.com> * src/ui, src/core, src/include: sort source files into these directories according to which part of the WM they are supposed to be in. In an eventual plan, we should also create src/compositor/render, src/compositor/fallback and move some of the compositor stuff into that. * autogen.sh: require a newer automake, so we don't have to use a recursive build * src/ui/tabpopup.c: put in a hack to make the build temporarily work, want to commit the large rearrangement before fixing this not to include workspace.h or frame.h * src/core/iconcache.c (meta_read_icons): temporarily break this to get the build to work, want to commit the large rearrangement before fixing this file not to include theme.h svn path=/trunk/; revision=3491
