lots of cleanups to the pango code, which was a very nice base to start from. thanks to whomever wrote that for us.. put some of the pango variables into the various render structs so that they don't need to be created all the time. put the pango context inside our RrInstance so that it can be properly freed at shutdown. removed xft dependencies all through the code and the build system also. who knows if this will break compiling for some poor souls. i guess we'll find out, won't we!
1. some random compiling/style cleanups
2. some bigfixes
- mislogic in per-window-settings and focusing new windows
- use client_can_focus rather than checking variables for directional focus
- MAYBE fix all those lock-ups forever. using event_curtime (a new variable) now instead of event_lasttime. event_lasttime is still used however when the event being processed did not have a time associated with it. this may or may not be a problem, and will be seen.
3. um.. i forget
4. oh yeah, 3rd party docks are now treated like the internal ob dock irt focus. that is, clicking on them won't pass them focus. this is going to be ratified as expected behavior in the wm-spec just now. if docks/panels want focus they can request it with _net_active_window, and then they can have all the focus they want! one day alt-tabbing around dock windows might be nice. but not until the ob dock is moved out into a separate application. going to have to add a wmapp selection and stuff for that though... ugly. who uses wmdockapps anymore !? someone must.. *sigh*
lots of modifications to the render API, prefixing everything, making proper
names for everything. the structures are not hidden/opaque yet, but the naming scheme of the public API works much better now.
client.c stacking.c: fixing looping transient case for group transient windows. now a window which is transient for a group is *not* transient for any other transient windows in the group (perviously the other window had to be transient for the group to be excluded, now it can be transient for anything).
client.c/h event.c render.c/h: adjustnig icon handling a bit. will be converting the legacy pixmap icons into rgba data so they can be handled the same as netwm icons.
