If we don't xcb_flush() when we set the selection owner, we end up with
a ridiculous corner case where we can run use a command line X client
like 'xclip -i -selection clipboard' to crash weston.
Start weston, ensure Xwayland is running (set a selection with xclip), set
the clipboard from a wayland client, then set the clipboard with xclip
again.
Since xclip doesn't do anything xwm notices except set the clipboard, it
won't provoke a flush on our selection ownership change. xclip will take
ownership, then we call xcb_convert_selection(), and THEN we flush, sending
out our pending ownership change and the xcb_convert_selection() request.
The ownership change takes place first, we attempt to get our own selection
and weston explodes in a mess.
Stop this from happening with a flush when changing selection ownership.

As things are, even when mode=current is specified on the .ini file,
a full modeset is needed (and done), which causes a very noticeable
screen blinking. That is because setting the max_bpc on a connector
needs full modesetting.
The idea here is that if mode=current on the .ini, no modesetting
should be done, so the current max_bpc is programmed into the
connector.
But if a custom max-bpc=... is specified, that will be used instead,
even if mode=current on the .ini

Surface views that are not assigned to a layer are not going to be
rendered, and thus should not participate in determining the outputs the
surface is on.
There are other view properties that may determine if the view should be

for this currently breaks tests. Such additional checks are left for

in the latter builddir checking
$ diff -ru -x '*.md5' -x '*.pdf' ~/tmp/weston-doc-before doc

The planes in the plane_list must be sorted from largest zpos_max to smallest.
Currently the plane order is only correct when the planes are already ordered
and added starting with the smallest zpos_max. This works accidentally in most
cases because the primary plane is usually first and there is often only one
overlay plane or the zpos is sufficiantly configurable.
To fix this, insert a new plane before the first plane with a smaller zpos_max.
And if none is found, insert it at the end of the list.
