The port is kind of evil, in that it stores either a PangoFontFamily or a
PangoFontFace in the list, depending on if the fontchooser is configured
to select fonts or faces.
It also does not cache the font description anymore, so more calls to
pango_font_describe() may happen.
If both of these issues turn out problematic, the fontchooser would need
to resurrect GtkDelayedFontDescription again and put objects of that
type through the model.
These changes depend on Pango 1.46's introduction of listmodels and
various new getters, so the dependency has been upgraded.
We don't want wrapping labels to cause tooltips to
have excessive height, so we need to set a reasonable
value for width-chars, without forcing short tooltips
into a full line length. Also be careful to respect
preexisting line breaks (we have such examples in
widget factory).
This commit is porting GtkPaned to be derived
from GtkWidget instead of GtkContainer, while adding
start-child and end-child properties. The existing
properties are renamed to follow the start/end naming
scheme, and we add proper getters and setters.
Update all users.

We want to remove GtkBin and GtkContainer as they don't
provide much useful functionality anymore. This requires
us to move get_request_mode and compute_expand down.
Update the accessible implementation to match, remove
remnants of container implementations in GtkWindow
subclasses, and fix livecycle issues around destroy
vs dispose in GtkAssistant.
After this commit, using gtk_container_add on window
subclasses is not allowed anymore, but adding childing
with <child> in ui files still works.
See #2681
The viewport draws a frame at the same place as
the scrolled window, so there is really no need
to have that ability in both. Just drop the frame
from viewports.
Make GtkScaleButton a widget that has a toggle button
as a child, just like all the other button widgets now.
The immediate benefit of this arrangement is to avoid
the "double focus" problem when we pop up the popup.
Update accessible, demos and tests to match.
This is one of the situations, where can-focus can still
be used to tweak focus behavior of leaf widgets. Color
swatches are focusable by default to allow selecting colors
with the keyboard. But when used as color samples, they
should not take focus.
When no printer has been selected (e.g. because we don't
find any printers), the 'print at' radio group should be
insensitive, except for the 'now' choice. Selecting another
option in this situation will lead to a crash.
