Add a way to toggle debug output on and off
from the inspector. For now, we don't add a
log viewer here, since that has the risk of
deadlock until we've the logging completely
separated by display, and also requires us
to install a log writer function, which
libraries are not supposed to do.
As far as possible, use per-display debug flags.
This will minimize the debug spew that we get from
the inspector if it is running on a separate display.
There are too many stack elements in the main stack. So add a substack
for the pages that display common global state. The appropriate name I
found for it was "Global".
It's used to house the General, Visual, Resources and Statistics pages
for now.
Instead, add a function gtk_image_set_icon_size() for the cases where
overriding the icon size is necessary.
Treat icon sizes the same way as pixel sizes, too. So gtk_image_clear()
no longer unsets the icon size.
Change constructors to reflect that.
While doing so, also add a fallback argument to the cursor constructors,
so it is now possible to create cursors with fallback.
Move the default pos of the Paned handle to 400px from the left, i.e.
50% of the default width of the window. The previous position at 300px
from left meant the node treeview was too narrow & could easily result
in the (useful) State column not being visible in the case of many
apps. The properties pane doesn't need to be as big as it was anyway.

The copy of the PangoGlyphString we do here was showing up
in some profiles. To avoid it, allocate the PangoGlyphInfo array
as part of the node itself. Update all callers to deal with
the slight api change required for this.
Rename the surface getter to peek, following other render
node getters, and make the surface-based constructor private,
since it is not something we want to encourage.
Update all callers.
This patch makes that work using 1 of 2 options:
1. Add all missing enums to the switch statement
or
2. Cast the switch argument to a uint to avoid having to do that (mostly
for GdkEventType).
I even found a bug while doing that: clearing a GtkImage with a surface
did not notify thae surface property.
The reason for enabling this flag even though it is tedious at times is
that it is very useful when adding values to an enum, because it makes
GTK immediately warn about all the switch statements where this enum is
relevant.
And I expect changes to enums to be frequent during the GTK4 development
cycle.
-Wint-conversion is important because it checks casts from ints to
pointers.
-Wdiscarded-qualifiers is important to catch cases where we don't
strings when we should.
