Horizontal scrolling is unusual, but specifying some extra offscreen
space for it in free in the normal case where the viewport is the
same width as the canvas anyway, so lets do it.
This patch uses GtkPixelCache to render the contents of the widget,
and typically a bit more, to an offscreen surface. The pixel cache in
turn manages rendering to the actual surface for the widget.
The current strategy for the size to render is the size of the widget
plus half the height.

Attached widgets inherit from the style of the widget they are
attached to. This can sometimes have unintended consequences,
like a context menu in the main view of gedit inheriting the font
that is configured for documents, or the context menu of the preview
in the font chooser coming up with humongous font size.
To fix this problem, we introduce a context menu style class
and use it for all menus that are used like that. The theme
can then set a font for this style class.

This reverts commit b2e666bf8f.
We need to keep cursor blinking configurable for accessibility
reasons.

When trying to drag, we currently the position of the first motion
event to determine where the drag came from. This might be alright
in the case of the old animation, but the data will be inaccurate
if the user has moved the pointer quite a bit since pressing the
cursor to start dragging. While we could monkey patch the GdkEvent
at the widget layer, this is unintuitive and strange.
Add a new API that takes a set of pointer coordinates describing
the origin of the drag. Additionally, adapt most widgets to use
it and use it with correct coordinates.

We've recently a number of classes wholly. For these cases,
move the headers and sources to gtk/deprecated/ and adjust
Makefiles and includes accordingly.
Affected classes:
GtkAction
GtkActionGroup
GtkActivatable
GtkIconFactory
GtkImageMenuItem
GtkRadioAction
GtkRecentAction
GtkStock
GtkToggleAction
GtkUIManager
We do this by making the ::populate-popup signals a little more
flexible. They used to just accept a GtkMenu as argument, now
they can take a menu or a toolbar. To not break the expectations
of existing callbacks, we only emit ::populate-popup with a toolbar
if the :populate-toolbar property is TRUE.
Don't set handles mode to none if the event has send_event set.
For consistency with GtkEntry, also make GtkTextView keep the
handle mode on buffer changes.
We always need to render the background, as the window
background is not always set (i.e. during gtk_widget_draw()) or
when its partially visible.

This replaces the previously hardcoded calls to gdk_window_set_user_data,
and also lets us track which windows are a part of a widget. Old code
should continue working as is, but new features that require the
windows may not work perfectly.
We need this for the transparent widget support to work, as we need
to specially mark the windows of child widgets.

This commit exposes the get_type() functions and standard
headers for accessible implementations. This makes it possible
to derive from the GTK accessible implementations without
GType magic tricks. This is necessary, because we require the
a11y type hierarchy to be parallel to the widget type hierarchy.
So, if you derive a widget and need to adjust its a11y implementation,
you have to be able to derive its accessible implementation.
This commit probably exposes more than is absolutely necessary,
it also exposes accessibles of widgets that are unlikely candidates
for deriving from.
GtkTextHandle is used to indicate both the cursor position
and the selection bound, dragging the handles will modify
the selection and scroll if necessary.
Backwards text selection is also blocked for touch devices,
so the handles don't get inverted positions and possibly
obscure portions of the selected text.
Instead, just draw the children. The cairo code will keep track of
things, so there's no need to track things.
Also, the old code was doing it wrong.

This can cause lagging when scrolling as it causes us to repaint
on every scroll event. This wasn't historically a great problem,
but with smooth scrolling we get a lot more events, so this
now creates visible lagging on slower machines.
Without any extra supporting code, just adding GTK_SMOOTH_SCROLL_MASK to
the event mask for GtkTextView makes GEdit do the right thing and scroll
smoothly. Lovely.

The widget window is usually covered by the bin_window.
Its background color will become relevant when we introduce
kinetic scrolling with overshooting.
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.

When multiple pointers are in play, we need to be careful
not to loose track of the device between receiving a button
press and popping up a menu.
