We need to make sure we drop reference on all exit paths through the
hide callback - somehow this only seemed to break internal windows.

this function is only called when screen geometry (or useful geometry) has
changed, and so all clients should have their geometries checked at this point
to ensure that they update for any new zone obstacle changes which have occurred
Wayland buffers are currently either ARGB or XRGB - we don't need to
convert either of these, we just need to set alpha appropriately - which
we now do.
This code is similar to code in weston, but doesn't really work properly
for us in E, since this can blow up buffers behind the async renderer's
back.
The rest of the reference code has been pushed into e_pixmap, so we can
kill this all now.
We need to keep wayland buffers around even if they'll never be written
to again. This is part of Buffer_Reference's task in weston, but we
already have our pixmap abstraction which can serve mostly the same
purpose.
Remove the "buffer reference" stuff from e_pixmap and replace it with a
kept buffer for the last commit.
Add shared memory pool references to keep pools from going away on us.
We need to make sure wayland clients aren't deleted while the scene
graph has their data pointers, so we take an extra reference when creating
them.
We drop that reference by clearing the client's image data and putting it
in the render post_updates list.
In wayland we can be presented with a new frame before being deleted. If
we've never displayed that frame we should (since we released all pointers
to the old frame when we got the new one)
we free the instance layout even though tthis is never duplicated but
jhust set to point to the current_layout. don't free it as this causes
a double-free. this fixes a crash here.
@fix
if multiple x11 clients receive focus during the same mainloop iteration,
an almost unbreakable cycle of window focus chaining will occur, resulting in
both windows being focused simultaneously--or so it appears--which results in
no window being able to receive input. to avoid this, ensure that only one x11
client can receive focus in a given loop iteration
due to event bursts, it's possible for multiple x11 clients to receive
mouse in events on during the same main loop iteration. in this scenario,
only the last client has received an actionable mouse in, and applying this
event after the dispatch has completed ensures that multiple clients do not
all receive mouse in+out events during the same loop
this greatly improves mouse-based focus reliability in a number of cases
mousing over a window for an x11 client should always yield x11 mouse events
in cases where mouse eventing is required; any events occurring on the comp
object in other cases inside the xwindow region are able to be ignored
the current security policy for this is based on two points:
1) don't add gadgets to your lockscreen that you don't want on your lockscreen
2) see #1
future improvements here will probably add gadget info to show what risks a gadget
may incur when placed on the lockscreen
