With the stock system being deprecated now, we should provide
meaningful accessible names for buttons that are constructed
from icon names or GIcons. This commit reuses the existing
translations.
It is possible that some common icon names are not covered
here because they were not present as stock items. These can
be added to the table later.
Discovered via a crash because b's (dest's) toplevel was NULL;
ensuring that the dest is actually a GdkWindow or setting b to NULL
prevents that path from being taken.
Spinners are essentially animated symbolic icons. We don't really
want them being rendered to arbitrary sizes. Also the current
technique for rendering the activity is not suitable for larger
sizes. Until we have a better technique we should limit the size
to the MENU icon size or exactly twice that size.
The 'direction' parameter to gtk_widget_keynav_failed() is based on
gtk_list_box_move_cursor()'s 'count' parameter. However if the passed
in movement is GTK_MOVEMENT_DISPLAY_LINES, 'count' is modified by
the keynav handling and will always be 0. To avoid messing up the
'direction' parameter, use a local variable for keynav handling and
leave 'count' untouched.

Previous commit wrongly identified "active" as containing the new
value. Instead, applications must determine the new value to
update the model with manually based on the value currently in the
model.
Clarify that applications are expected to handle updating the model
from the 'active' property, like GtkCellRendererText does for the
'edited' property.
This test demonstrates that various deprecated ways
to construct buttons and menuitems still work as they
are supposed to, including always-show-image functionality.
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.
