If a GtkScrollable uses a different scale than pixels the offset from a
drag must be adjusted to match this scale. This fixes issues like this
https://gitlab.gnome.org/GNOME/vte/-/issues/283 where the terminal
widget uses rows instead of pixels as its scale for each GtkAdjustable
thus causing a 1 pixel vertical drag to scroll 1 row.
In gtk_tree_view_build_tree with recurse=TRUE, the TEST_EXPAND_ROW
signal might invalidate the child iterator. Getting the iterator after
the signal (instead of before) fixes the issue.

Path concatenation is much nicer than the unwieldy format method.
Since paths returned by get_option are relative to prefix, they will be joined as before.
As a bonus, this fixes weird platforms like NixOS that actually pass absolute includedir under a different prefix.
Due to the deprecation in gtkshow.h, there is proper deprecation warning
for C code. But, for bindings (python in one case), there is no warning,
due to missing "Deprecated:" annotation in gtkshow.c

When a fixed size is active (e.g. the window is maximized),
gtk_window_resize() shouldn't take immediate effect, so the request was
dropped. This made GTK unhappy if this happened, it will freeze updating
the window until it received the new size it demanded.
Handle this by being nice and emitting a dummy GDK_CONFIGURE event with
the old size where we previously ignored it. It won't resize the window
immediately, so it shouldn't have a visible effect, and the size GTK
requested is still saved away for when the window is unmaximized, but
emitting the event will make GTK receive the event it expects.
We still drop the request on the floor, e.g. if we still haven't seen
the initial configuration, just as we do when actually doing the resize.
