0dbdf0c428 gadget: Remove gtk_css_gadget_draw() 
And with it, remove the draw func from custom gadgets, that has been
NULL everywhere.

All gadgets are snapshot now.

8507083928 levelbar: update css nodes even when no offset value is found 
GtkLevelBar supports adding custom offsets as style classes, and they
are applied whenever the :value property matches. The current code,
however, only updates any CSS nodes when an offset is found, causing
it to not update when a discrete value changes but no custom offset
is added.

Fix that by always updating the CSS nodes.

9992a616ef widget: Use ::measure vfunc to measure size 
Add a new ::measure vfunc similar to GtkCssGadget's that widget
implementations have to override instead of the old get_preferred_width,
get_preferred_height, get_preferred_width_for_height,
get_preferred_height_for_width and
get_preferred_height_and_baseline_for_width.

e1a03ead7a Use NULL for generic marshallers in g_signal_new() 
glib will use the correct marshaller automatically. And as a side
effect, we also get all glib optimizations, like a va marshaller.

37007c47a5 level bar: Don't leave css nodes behind 
We create and destroy gadgets inside the levelbar hierarchy here,
and if we don't explicitly remove their CSS nodes from the parent,
they stick around.

c784d5d700 levelbar: Avoid a use-after-free 
We were freeing the old offset before using its name to
recreate a new one. Don't do that.
Found by gcc's undefined behavior sanitizer.

ccd8c76ff2 level bar: Fix offset behavior 
We had some odd special-casing for the lowest and highest offset
that did not quite work. The new rule is simple: If the value
is between offset n-1 and n, it gets the style for offset n.

1a71579b61 level bar: Improve documentation

changed.

third one, and mention it in the docs.

61307deaf7 levelbar: Make discrete levelbars behave as before 
During the gadget conversion, the drawing of discrete levelbars
was unintentionally changed to draw a wide trough but narrow
blocks, which does not look great. So go back to the previous
way of drawing things.

Use gtk_css_gadget_set_state in all the places where we previously
were getting a node from a gadget, just to call gtk_css_node_set_state.

637ade656a levelbar: loop over all block gadgets to determine min size 
Instead of just picking the first. This is because the theme might set a
border on only one of them, like the HighContrast theme does.

971a277419 cssnode: Change style-changed signal 
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.

afd6621743 GtkLevelBar: Use the new helpers 
Instead of issuing g_warning, fill the provided GError.
This lets us test this error handling, and is the right
thing to do. Use the new GtkBuilder helpers and
g_markup_collect_attributes to do so.

631e2f4c9b levelbar: don't use the current value style class for empty blocks 
We want to be able to style the empty blocks independently of all the
offset styles, so remove the current style class when painting an empty
block.

37a8ee6e95 docs: fully break lines in examples 
Try to do a better job of keeping example content
from being too wide. It is often rendered as <pre>
text so the only time we can wrap it is in the source.

It is best to full break lines at all punctuation and
to try to keep the width under 70 chars or so.
