When a GtkRadioButton has no focus, it will accept it when there is no
other active button in its group.
If the active button in the group is hidden, for example because the UI
desires not to have a default option pre-selected, currently the focus
will not be accepted, which is not desired behavior.
This commit changes the code to only consider visible buttons in the
group when checking whether another button is active.

Stop using activate-on-single click for the property list -
it is a little annoying to have the popover come up when you
just click in the list to get the focus there.
This restructures the way buffers are allocated and bound in a way
that is more flexible.
Buffer operation happens in three phases:
create_buffer() - Creates the gl objects
allocate_buffers() - Allocates space for the buffers at a given size
attach_buffers() - Attaches the buffers to the framebuffer and makes
the framebuffer the default drawing target
And destroy via
delete_buffers()
We call all these the first draw, and after that we allocate buffers
each time the widget changes size until the buffers are deleted.
We delete the buffers at unrealize.
However, anyone that wants to manually control buffer allocation strategies
can manually call allocate/delete_buffers().
There are also some other changes:
* Support for stencil buffers.
* A manual render mode where ::draw doesn't render unless you manually
invalidated the previous rendering.
We had some code that tried to reuse the context over realize, but
that doesn't work as we need to share with the possibly new
paint context of the re-realized window.
Removed bright translucent outer border for "top level" osd widgets,
insensitive osd entry styled, more meaningfull color variables and
some code rationalization.
Add a menu-name property and use it in a default implementation
of ::clicked to switch menus if we are inside a stack. This means
GtkModelButton is no longer entirely generic, but rather expects
to be used inside a GtkPopoverMenu. It still works in other contexts
too, of course.
Rename the "toggled" property to "active", since that is what
GtkActionHelper expects to update for check and radio actions.
Also make the property readable, since GtkActionHelper wants
to read it.
Under wayland, the compositor doesn't have a 'overall window alpha'
knob, we just need to add the alpha to the buffers we send.
Client-side alpha, if you want to call it that.
Implement this by reusing the existing alpha support for non-toplevel
widgets. As a side-effect of the implementation, windows with RGBA
visual under X will now also use per-pixel alpha, instead of
overall alpha.
