If the scale has an origin (it will have one by default), GtkRange will
render the two sides before/after the current value with different style
classes, making it possible for themes to use different colors and
properties for the two areas.
This was possible in GTK 2 with style details, but got lost during the
road to 3.0.

GtkRange needs to check if its allocation intersects with the resize
grip allocation (trimming its own allocation if it does).
In order to do that, it needs to translate its allocation into window
coordinates, and before that, find the window to whose the allocation
is relative; code goes all the way finding the right parent widget, but
then doesn't actually use it when translating the coordinates, leading
to using the wrong rectangles for the intersection check.

This commit introduces a new setting, gtk-visible-focus, backed
by the Gtk/VisibleFocus X setting. Its three values control how
focus rectangles are displayed.
'always' is equivalent to the traditional GTK+ behaviour of always
rendering focus rectangles.
'never' does what it says, and is intended for keyboardless
situations, e.g. tablets.
'automatic' hides focus rectangles initially, until the user
interacts with the keyboard, at which point focus rectangles
become visible.

Commit 4bb3d64414 introduced a limitation
to GtkRange style properties; when stepper-spacing is > 0,
trough-under-steppers is automatically set to FALSE; this means that
setting a spacing between the steppers (e.g. the scrollbar buttons) and
the trough (i.e. the area over which the slider is free to move) would
make the buttons always get the full allocation on the !orientation
direction.
The rationale is without this limitation, you would get an area which
seems clickable, but it's actually not.
While this is true, and undesirable, for big stepper spacings, themes
that use trough-under-steppers (which is TRUE by default anyway),
might want to set smaller spacings to avoid drawing a double line between
the button and the slider borders.
To add confusion, the documentation got it flipped, i.e. it stated
setting a positive stepper-spacing would set trough-under-steppers to
TRUE (which would also make the behavior expected by commit
4bb3d64414 impossible).
I don't think hardcoding either of the two limitations is a good thing.
We should let themes handle this instead, and remove this limitation. If
you want the old behavior, you can manually set trough-under-steppers to
FALSE if you set a positive stepper-spacing in your theme.

GtkFileChooserDefault watches the toplevel and montitors "set-focus"
signal on it... however the connection needs to be remade when the
GtkFileChooserDialog is in an embedded toplevel.
Measure's taken: GtkWindow propagates hierarchy changes when
_gtk_window_set_is_toplevel() is called, gtk_widget_unparent()
unsets the widget's parent window earlier in the function so that
the possible hierarchy change is still able to properly access the hierarchy.
GtkFileChooserDefault checks if the "new" toplevel is indeed
gtk_widget_is_toplevel() but not the old one, GtkRange has been
updated to use gtk_widget_is_toplevel() inside it's hierarhcy_changed
vfunc, other classes already do this properly.
We need to be a little more careful when determining the overlap
between the new allocation and the grip area. This was causing
vertical scrollbars in evince to overlap with the grip.
If there are both horizontal and vertical scrollbars, there is
an unused 'corner' into which the resize grip fits. Individual
scrollbars need to be shortened and moved to make room for the
resize grip.
The keysyms create a lot of potential namespace conflicts for
C, and are especially problematic for introspection, where we take
constants into the namespace, so GDK_Display conflicts with GdkDisplay.
For C application compatiblity, add gdkkeysyms-compat.h which uses
the old names.
Just one user in GTK+ continues to use gdkkeysyms-compat.h, which is
the gtkimcontextsimple.c, since porting that requires porting more
custom Perl code.
This was a style property to let theme engines 'opt-in' to more
correct behaviour while maintaining compatibility with existing
themes. GTK+ 3 engines are expected to handle the more correct
behaviour.
