If a range goes all the way to the edge of the screen then we don't
have any way to activate autoscrolling. By adding a small region
at the ends of the range we can handle this case. This is the same
approach used in treeviews.
If we're going to run off the end due to an invalid message,
we're going to run off the end. We'll protect this by doing
proper bounds checking in the future, but the malloc gives
us nothing for now.
The newly-added gtk_flow_box_child_is_selected() needed to return a
gboolean, so use g_return_val_if_fail() to return FALSE when an invalid
GtkFlowBoxChild* is passed in.
Make flowbox selection more orthodox. Control and Shift now
modify the selection behaviour pretty much in the same way
they do in a tree view, and clicking without modifiers will
clear the selection.
When dealing with touch devices, we treat modifier-less events
as modifying the selection.
This commit also adds a few other selection necessities, such
as catching Escape key presses to cancel rubberband selection,
and handling grab notify.
GtkFlowBox is a container that its children in a reflowing
grid, which can be oriented horizontally or vertically.
It is similar to GtkListBox in that the children can
be sorted and filtered, and by requiring a dedicated child
widget type, GtkFlowBoxChild. It is similar to GtkTreeView
in that is supports a full set of selection modes, including
rubberband selection.
This is the culmination of work that has happened in the
egg-list-box module, and earlier in libegg. The origins of
this code are the EggSpreadTable in libegg, which was written
by Tristan van Berkom. It was moved to egg-list-box and
renamed EggFlowBox by Jon McCann, and I gave it some finishing
touched in the flowbox-improvements branch of that module.
Previously, the "Places" sidebar was populated by the update_places()
call from within gtk_places_sidebar_style_set(). After
742a2f11a9, update_places() is never called
and the sidebar is never populated unless gtk_places_sidebar_add_shortcut()
happens to be called. This commit fixes this by calling update_places()
at the end of gtk_places_sidebar_init().

The docs for GtkPlug/GtkSocket were not generated if any
of the win32, quartz, wayland backends were enabled. What
we really mean though, is that we want the docs to be generated
whenever GtkPlug/GtkSocket are included in the library, which
is when the x11 backend is enabled.
As long as we are not ready to switch over the default backend,
arrange ./configure without explicit backend options makes the
x11 backend mandatory and the wayland backend optional (depending
on whether we find Wayland dependencies).

GtkWidget had a hack where if opacity is 0.999 we set up an opacity group when
rendering the widget. This is no longer needed in 3.10, and GtkStack doesn't
use it anymore.
GdStack is using it, so applications should be ported from GdStack to GtkStack
in 3.12.

Resize modes don't work anymore, both because nobody ever uses them and
because the frame clock changed the way things work quite a bit. So we
don't want to advertise them as a good idea.
