This was used with GTK2, but is now unnecessary as discussed in bug 1278282.
moz_gtk_init() is now called from only one place and so will be called only
once.

Changes in behavior are intended to be minimal, but this adds distinct
metrics for horizontal and vertical scrollbars even with GTK versions < 3.20.
Updates on theme changes will be restored in a subsequent patch.

There is no need to calculate thumb borders because thumb border-box sizes are
determined with GetMinimumWidgetSize, which includes GTK margin, border, and
padding, and the interior border width is irrelevant because thumbs have no
children.

This is consistent with GTK not setting these flags with GtkTextView
and GtkScrolledWindow.
The active flag was triggering @selected_bg_color with Ambiance.
This patch almost reverts the state flags to the logic prior to
cd7544affe40 but keeps the focused flag in the scrolled window.

The style context for MOZ_GTK_TEXT_VIEW is now created by copying from the
widget instead of caching a widget and using its context.
No rendering changes are expected, unless themes are animating GtkTextView
backgrounds.

In GTK 3.20, gtk_menu_item_draw() just draws the root widget gadget, depending
on the theme to style menu items with CSS name "separator" appropriately.

The GtkContainer border-width property defaults to zero. It is not influenced
by theme CSS. While theme engines can theoretically modify default values for
properties of any class, I don't think that is something that needs to be
supported.
Removing this code is necessary to switch from caching GtkWidgets to caching
GtkStyleContexts only.

Tooltip widget is made in GTK3 as following tree:
* Tooltip window
* Horizontal Box
* Icon (not supported by Firefox)
* Label
Each element can be fully styled by CSS of GTK theme so we have to draw all
elements with appropriate offset and full box model.

The Gtk 3.20 scrollbars has moved towards usual box model. The scrollbar,
trough,thumb and scrollbar button can now have margin, padding and border set,
different for each direction (ie. left, right, bottom, top). The scrollbar
metrics become ignored in Gtk 3.20 and later.
* Draw scrollbar element [for GTK 3.20+]
* The border for scrollbar, trough, thumb and scrollbar buttons is newly
calculated as margin+padding+border [for GTK 3.20+].
* The margin is subtracted for scrollbar, trough and sb buttons during paint
function [for GTK 3.6+]
* All scrollbar widget's borders transfered from
nsNativeThemeGTK::GetWidgetBorder to the moz_gtk_get_widget_border.
* Added helper function NativeThemeToGtkTheme for mapping mozilla's widget type
to the gtk widget type.
* Scrollbar troughs are now drawn even when there is not enough room for
the thumb [GTK 3.20+]
