notebook: Don't store gadget allocation twice
...
If we care about a gadget's allocation, we can ask it. There's no need
to store it in GtkNotebookPage.allocation.

I also was too lazy to convert existing widgets.

gadget: Handle visibility
...
As GtkCssNode has the visibility concept, it makes sense to mirror it in
gadgets.
Do what visibility does in widgets: Hidden gadgets can't be drawn or
allocated and request a 0x0 size.
Note that just like widgets, gadget visibility must not be changed in
size request, allocate or draw handlers.
GtkWidget::child-visible has no equivalent yet, code will have to
emulate that manually.

gadget: Don't warn about unset clip
...
Instead of warning about an unset clip, simply ignore
empty content clips.

gadget: Avoid warning for empty containers
...
Empty boxes end up setting the clip to { 0, 0, 0, 0}, so warning
for a width or height of 0 triggers false positives. Instead,
initialize the clip to clearly invalid values.

gadget: Warn if clip is not set
...
This leads to hard-to-track-down drawing errors, so better
warn explicitly about it.

label: Position the text properly
...
The PangoLayout needs to be positioned according to the content
allocation of the gadget, not the widget's allocation.

We are making the allocation smaller, so the baseline

Instead of asserting if we hit negative content sizes,
warn and continue. This is easier to work with in this
transition period.

gadget: Add the concept of a "gadget"
...
A gadget is halfway between a widget and a CSS node. It's supposed to
provide the minimum convenicence around CSS nodes until we've figured
out how to integrate them with widgets.
