Commit afd9709aff made us keep impl window
cairo surfaces around across changes of window scale. But the
window scale setter forgot to update the size and scale of the
surface. The effect of this was that toggling the window scale
from 1 to 2 in the inspector was not causing the window to draw
at twice the size, although the X window was made twice as big,
and input was scaled too. Fix this by updating the surface when
the window scale changes.
We need to use this in the code path where we make the context
non-current during destroy, because at that point the window
could be destroyed and gdk_window_get_display() would return
NULL.
The child property setting must be prepared to deal with any
child property for any child, even if it doesn't make sense,
like the pack-type for the custom title. This is happening
in glade when undoing a change in the custom-title property.
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.
This moves the code related to the frame sync code into
the is_attached check, which means we don't have to ever
run this when making non-window-paint contexts current.
This is a minior speed thing, but the main advantage
is that it makes making a non-paint context current
threadsafe.
