Previously, we were only showing the size of the allocation
and clip area. But there is no good reason to hide the position
of these rectangles, so add them, in the traditional format
of X geometry strings: wxh+x+y
While rescanning the object tree, we were emitting ::object-selected
signals, possibly causing wild blinking in the application window.
Don't do that.

Constructing GtkCssStyleChange objects without styles is forbidden, so
don't do it. Instead untangle the callback from the actual update
function and call that untangled function directly.
Instead of having old and new style, now have a GtkCssStyleChange opaque
object that will compute the changes you are interested in for you.
This simplifies change signal handlers quite a bit and avoids lots of
repeated computation in every signal handler.
Showing two lists in a paned was a bit awkward, and space was
getting too limited. Go back to showing just the node list at
first, and make the CSS properties available via a stack. At
the same time, add a right-click context menu to the node list
to make the name and class editing more easily available.
Empty underlines are hard to make out. Since we get somewhat
unreliable section information from the CSS parser, we just
make sure that we always underline at least one character.
The builder syntax for tags was invalid here (why did this not
get flagged as error ?!). While we're at it, give the warning
underline a nice, orange color.
This is kind of a hack the way it's implemented, but it's necessary
for performance to ignore transient nodes as they get created all the
time (via gtk_style_context_save()) and invalidate the whole treeview.
And that causes resizes and redrawing of the treeview and performance of
the inspector would go down the drain now that we display a larger part
of the node tree.
When the CSS style of a node changes, we want to display the new values
in the inspector.
This for example allows to see how styles update on hover or during
animations.
Sadly, interned string properties cannot be handled generically
at all - GObject insists on inserting a strcpy in any attempt
to set a string property with generic api, destroying the
internedness of the string.
Therefore, we have to special-case GtkCssNode in the property
editor code :-(
gtk_inspector_object_tree_find_object accesses the type information
of the object, so we can't safely use it on an already decaying
object when we get a weak notify. Instead just walk the tree and
compare pointers, that is safe.
