Руслан Ижбулатов 26c24328d5 GDK: Add cursor theme support to W32 backend 
Load themed cursors from the same places they are loaded on freedesktop systems,
but use W32 API functions to do so (works for .cur/.ani cursors instead of X
cursors).

Refactor the code for cursor handling. Prefer loading cursors by name.

Do not load actual cursors when loading the theme. Find the files and remember
the arguments/calls for loading them instead. Keeping HCURSOR instance in the
hashmap would result in multiple GdkCursors using the same HCURSOR. Given that
we use DestroyCursor() to off them, this would cause problems (at the very
least - DestroyCursor() would fail).

Store GdkCursor instances in a cache. Update cached cursors when theme changes.

Recognize "system" theme as a special (and default) case. When it is set,
prefer system cursors and fall back to Adwaita cursors and (as a last resort)
built-in X cursors. Otherwise prefer theme cursors and fall back to system and
X cursors.

Force GTK to use "left_ptr" cursor when no cursor is set. Using NULL makes
it use the system default "arrow", which is not the intended behaviour when
a non-system theme is selected.

Ignore cursor size setting and query the OS for the required cursor size, as
Windows (almost) does not allow setting cursors of arbitrary size.

/**
* SECTION:gtksettings
* @Short_description: Sharing settings between applications
* @Title: Settings
*
* GtkSettings provide a mechanism to share global settings between
* applications.
*
* On the X window system, this sharing is realized by an
* [XSettings](http://www.freedesktop.org/wiki/Specifications/xsettings-spec)
* manager that is usually part of the desktop environment, along with
* utilities that let the user change these settings. In the absence of
* an Xsettings manager, GTK+ reads default values for settings from
* `settings.ini` files in
* `/etc/gtk-3.0`, `$XDG_CONFIG_DIRS/gtk-3.0`
* and `$XDG_CONFIG_HOME/gtk-3.0`.
* These files must be valid key files (see #GKeyFile), and have
* a section called Settings. Themes can also provide default values
* for settings by installing a `settings.ini` file
* next to their `gtk.css` file.
*
* Applications can override system-wide settings by setting the property
* of the GtkSettings object with g_object_set(). This should be restricted
* to special cases though; GtkSettings are not meant as an application
* configuration facility. When doing so, you need to be aware that settings
* that are specific to individual widgets may not be available before the
* widget type has been realized at least once. The following example
* demonstrates a way to do this:
* |[<!-- language="C" -->
* gtk_init (&argc, &argv);
*
* // make sure the type is realized
* g_type_class_unref (g_type_class_ref (GTK_TYPE_IMAGE_MENU_ITEM));
*
* g_object_set (gtk_settings_get_default (), "gtk-enable-animations", FALSE, NULL);
* ]|
*
* There is one GtkSettings instance per screen. It can be obtained with
* gtk_settings_get_for_screen(), but in many cases, it is more convenient
* to use gtk_widget_get_settings(). gtk_settings_get_default() returns the
* GtkSettings instance for the default screen.
