gdk_window_get_update_area is supposed to get the area where things
need painting, and remove them from the update areas. However, if
some area is covered by other windows with an alpha background we
can't just expect whatever the app choses to render in the update
area as correct, so we don't actually remove these areas, meaning
they will get correctly rendered when we get to the expose handlers.
gdk_window_move_region doesn't move children, so we can't copy
transparent child window regions with copyarea, so we remove these
from the copy region.
We track the areas that have alpha coverage so that we can
avoid using these as sources when copying window contents.
We also don't remove such areas from the clipping regions so
that they are painted both by parent and child.
This cleans up the expose handling a bit by using the existing
clip regions, and it allows us later to use painters algorithm
to do transparent windows.
If no icon size is provided (e.g. when setting icon-name or stock-id
using the GObject property directly), use the default icon size. This
matches the previous GtkImage behavior.
The new function provides an API that takes the PangoLayout and index
as input params, this way it handles strong and weak cursors internally
factoring out all code duplicated in the widgets that need to render
cursors.

Explicitely check the split-cursor setting when drawing the textview
insertion cursor instead of relying on the cursor_direction set in the
textlayout. This makes the cursor drawin code more uniform with other
widgets in preparation to refactoring the cursor drawing code in a
shared function.

Move the handling of primary/secondary cursors to gtktextdisplay, which
makes code simpler and more consistent to how GtkLabel and GtkEntry
draw cursors, which is useful in preparation to further refactoring.

GtkIconHelper is a helper object to easily obtain a pixbuf from
different icon sources (e.g. a GIcon, an icon name, a stock id, ...).
Code is ported from GtkImage, which will be adapted in the next commit.
It used to be that _gtk_path_bar_set_file() would return an error if
it wasn't able to switch to the specified file, but that hasn't been
the case for a long while now, since the file chooser became async.

Previously, when the cursor was a descendant of the collapsed row,
the cursor path was set to the collapsed row, but this was not
communicated via cursor-changed events.
