MetaShapedTexture: save and restore textures on suspend

The proprietary nvidia driver garbles GPU memory on suspend. In order to workaround that limitation, this commit copies all textures to host memory on suspend and restores them on resume. One complication comes from external textures (such as those given to us by Xwayland for X clients). We can't just restore those textures, since they aren't writable. This commit addresses that complication by keeping a local texture around for those external textures, and using it instead for parts of the window that haven't been redrawn since resume.
background: purge all background textures on suspend

 # Style
 The coding style used is primarily the GNU flavor of the [GNOME coding
 style][gnome-coding-style], with some additions described below.
 ## General
 * Use this code style on new code. When changing old code with a different
   code style, feel free to also adjust it to use this code style.
 * Use regular C types and `stdint.h` types instead of GLib fundamental
   types, except for `gboolean`, and `guint`/`gulong` for GSource IDs and
   signal handler IDs. That means e.g. `uint64_t` instead of `guint64`, `int`
   instead of `gint`, `unsigned int` instead of `guint` if unsignedness
   is of importance, `uint8_t` instead of `guchar`, and so on.
 * Try to to limit line length to 80 characters, although it's not a
   strict limit.
 * Usage of `g_autofree` and `g_autoptr` is encouraged. The style to use is
    ```c
    g_autofree char *text = NULL;
    g_autoptr (MetaSomeThing) thing = NULL;
    text = g_strdup_printf ("The text: %d", a_number);
    thing = g_object_new (META_TYPE_SOME_THING,
                          "text", text,
                          NULL);
    thinger_use_thing (rocket, thing);
    ```
 * Declare variables at the top of the block they are used, but avoid
   non-trivial logic among variable declarations. Non-trivial logic can be
   getting a pointer that may be `NULL`, any kind of math, or anything
   that may have side effects.
 * Instead of boolean arguments in functions, prefer enums or flags when
   they're more expressive. The naming convention for flags is
    ```c
    typedef _MetaSomeThingFlags
    {
      META_SOME_THING_FLAG_NONE = 0,
      META_SOME_THING_FLAG_ALTER_REALITY = 1 << 0,
      META_SOME_THING_FLAG_MANIPULATE_PERCEPTION = 1 << 1,
    } MetaSomeThingFlags;
    ```
 * Use `g_new0 ()` etc. instead of `g_slice_new0 ()`.
 * Initialize and assign floating point variables (i.e. `float` or
   `double`) using the form `floating_point = 3.14159` or `ratio = 2.0`.
 ## Header (.h) files
 * The return type and `*` are separated by a space.
 * Function name starts one space after the last `*`.
 * Parenthesis comes one space after the function name.
 As an example, this is how functions in a header file should look like:
 ```c
 gboolean meta_udev_is_drm_device (MetaUdev    *udev,
                                  GUdevDevice *device);
 GList * meta_udev_list_drm_devices (MetaUdev  *udev,
                                    GError   **error);
 MetaUdev * meta_udev_new (MetaBackendNative *backend_native);
 ```
 ## Source code
 Keep functions in the following order in source files:
  1. GPL header
  2. Enums
  3. Structures
  4. Function prototypes
  5. `G_DEFINE_TYPE()`
  6. Static variables
  7. Auxiliary functions
  8. Callbacks
  9. Interface implementations
  10. Parent vfunc overrides
  11. class_init and init
  12. Public API
 ### Structures
 Each structure field has a space after their type name. Structure fields aren't
 aligned. For example:
 ```c
 struct _MetaFooBar
 {
  MetaFoo parent;
  MetaBar *bar;
  MetaSomething *something;
 };
 ```
 ### Function Prototypes
 Function prototypes must be formatted just like in header files.
 ### Overrides
 When overriding parent class vfuncs, or implementing an interface, vfunc
 overrides should be named as a composition of the current class prefix,
 followed by the vfunc name. For example:
 ```c
 static void
 meta_bar_spawn_unicorn (MetaParent *parent)
 {
  /* ... */
 }
 static void
 meta_bar_dispose (GObject *object)
 {
  /* ... */
 }
 static void
 meta_bar_finalize (GObject *object)
 {
  /* ... */
 }
 static void
 meta_bar_class_init (MetaBarClass *klass)
 {
  GObjectClass *object_class = G_OBJECT_CLASS (klass);
  MetaParentClass *parent_class = META_PARENT_CLASS (klass);
  object_class->dispose = meta_bar_dispose;
  object_class->finalize = meta_bar_finalize;
  parent_class->spawn_unicorn = meta_bar_spawn_unicorn;
 }
 ```
 ### Interface Implementations
 When implementing interfaces, two groups of functions are involved: the init
 function, and the overrides.
 The interface init function is named after the interface type in snake case,
 followed by the `_iface_init` suffix. For example:
 ```c
 static void meta_foo_iface_init (MetaFooInterface *foo_iface);
 G_DEFINE_TYPE_WITH_CODE (MetaBar, meta_bar, G_TYPE_OBJECT,
                         G_IMPLEMENT_INTERFACE (META_TYPE_FOO,
                                                meta_foo_iface_init));
 ```
 Then, when implementing each vfunc of the interface, follow the same pattern
 of the [Overrides](###Overrides) section. Here's an example:
 ```c
 static void
 meta_bar_do_something (MetaFoo *foo)
 {
  /* ... */
 }
 static void
 meta_foo_iface_init (MetaFooInterface *foo_iface)
 {
  foo_iface->do_something = meta_bar_do_something;
 }
 ```
 ### Auxiliary Functions
 Auxiliary functions are above every other functions to minimize the number of
 function prototypes in the file. These functions often grow when factoring out
 the same code between two or more functions:
 ```c
 static void
 do_something_on_data (Foo *data,
                      Bar *bar)
 {
  /* ... */
 }
 static void
 random_function (Foo *foo)
 {
  do_something_on_data (foo, bar);
 }
 static void
 another_random_function (Foo *foo)
 {
  do_something_on_data (foo, bar);
 }
 ```
 Sometimes, however, auxiliary functions are created to break down otherwise
 large functions - in this case, it is appropriate to keep these auxiliary
 functions close to the function they are tightly related to.
 Auxiliary function names must have a verb in the imperative form, and should
 always perform an action over something. They usually don't have the class
 prefix (`meta_`, `clutter_`, or `cogl_`). For example:
 ```c
 static void
 do_something_on_data (Foo *data,
                      Bar *bar)
 {
  /* ... */
 }
 ```
 Exceptionally, when converting between types, auxiliary function names may
 have the class prefix to this rule. For example:
 ```c
 static MetaFoo *
 meta_foo_from_bar (Bar *bar)
 {
  /* ... */
 }
 ```
 ### Callback Functions
 Callback function names should have the name of the action in imperative
 form. They don't have any prefix, but have a `_func` suffix. For example:
 ```c
 static void
 filter_something_func (Foo      *foo,
                       Bar      *bar,
                       gpointer  user_data)
 {
  /* ... */
 }
 ```
 ### Signal Callbacks
 Signal callbacks generally have the signal name. They should be prefixed with
 `on_`, or suffixed with `_cb`, but not both. For example:
 ```c
 static void
 on_realize (ClutterActor *actor,
            gpointer      user_data)
 {
  /* ... */
 }
 static void
 destroy_cb (ClutterActor *actor,
            gpointer      user_data)
 {
  /* ... */
 }
 ```
 When the callback is named after the object that generated it, and the signal,
 then passive voice is used. For example:
 ```c
 static void
 click_action_clicked_cb (ClutterClickAction *click_action,
                         ClutterActor       *actor,
                         gpointer            user_data)
 {
  /* ... */
 }
 ```

 # Mutter
 Mutter is a Wayland display server and X11 window manager and compositor library.
 When used as a Wayland display server, it runs on top of KMS and libinput. It
 implements the compositor side of the Wayland core protocol as well as various
 protocol extensions. It also has functionality related to running X11
 applications using Xwayland.
 When used on top of Xorg it acts as a X11 window manager and compositing manager.
 It contains functionality related to, among other things, window management,
 window compositing, focus tracking, workspace management, keybindings and
 monitor configuration.
 Internally it uses a fork of Cogl, a hardware acceleration abstraction library
 used to simplify usage of OpenGL pipelines, as well as a fork af Clutter, a
 scene graph and user interface toolkit.
 Mutter is used by, for example, GNOME Shell, the GNOME core user interface, and
 by  Gala, elementary OS's window manager. It can also be run standalone, using
 the  command "mutter", but just running plain mutter is only intended for
 debugging purposes.
 ## Contributing
 To contribute, open merge requests at https://gitlab.gnome.org/GNOME/mutter.
 It can be useful to look at the documentation available at the
 [Wiki](https://gitlab.gnome.org/GNOME/mutter/-/wikis/home).
 ## Coding style and conventions
 See [HACKING.md](./HACKING.md).
 ## Git messages
 Commit messages should follow the [GNOME commit message
 guidelines](https://wiki.gnome.org/Git/CommitMessages). We require an URL
 to either an issue or a merge request in each commit. Try to always prefix
 commit subjects with a relevant topic, such as `compositor:` or
 `clutter/actor:`, and it's always better to write too much in the commit
 message body than too little.
 ## Default branch
 The default development branch is `main`. If you still have a local
 checkout under the old name, use:
 ```sh
 git checkout master
 git branch -m master main
 git fetch
 git branch --unset-upstream
 git branch -u origin/main
 git symbolic-ref refs/remotes/origin/HEAD refs/remotes/origin/main
 ```

 # We support a fairly large range of possible variables.  It is expected that all types of files in a test suite
 # will belong in exactly one of the following variables.
 #
 # First, we support the usual automake suffixes, but in lowercase, with the customary meaning:
 #
 #   test_programs, test_scripts, test_data, test_ltlibraries
 #
 # The above are used to list files that are involved in both uninstalled and installed testing.  The
 # test_programs and test_scripts are taken to be actual testcases and will be run as part of the test suite.
 # Note that _data is always used with the nobase_ automake variable name to ensure that installed test data is
 # installed in the same way as it appears in the package layout.
 #
 # In order to mark a particular file as being only for one type of testing, use 'installed' or 'uninstalled',
 # like so:
 #
 #   installed_test_programs, uninstalled_test_programs
 #   installed_test_scripts, uninstalled_test_scripts
 #   installed_test_data, uninstalled_test_data
 #   installed_test_ltlibraries, uninstalled_test_ltlibraries
 #
 # Additionally, we support 'extra' infixes for programs and scripts.  This is used for support programs/scripts
 # that should not themselves be run as testcases (but exist to be used from other testcases):
 #
 #   test_extra_programs, installed_test_extra_programs, uninstalled_test_extra_programs
 #   test_extra_scripts, installed_test_extra_scripts, uninstalled_test_extra_scripts
 #
 # Additionally, for _scripts and _data, we support the customary dist_ prefix so that the named script or data
 # file automatically end up in the tarball.
 #
 #   dist_test_scripts, dist_test_data, dist_test_extra_scripts
 #   dist_installed_test_scripts, dist_installed_test_data, dist_installed_test_extra_scripts

 /**
 * SECTION:clutter-blur
 * @short_description: Blur textures
 *
 * #ClutterBlur is a moderately fast gaussian blur implementation.
 *
 * # Optimizations
 *
 * There are a number of optimizations in place to make this blur implementation
 * real-time. All in all, the implementation performs best when using large
 * blur-radii that allow downscaling the texture to smaller sizes, at small
 * radii where no downscaling is possible this can easily halve the framerate.
 *
 * ## Multipass
 *
 * It is implemented in 2 passes: vertical and horizontal.
 *
 * ## Downscaling
 *
 * #ClutterBlur uses dynamic downscaling to speed up blurring. Downscaling
 * happens in factors of 2 (the image is downscaled either by 2, 4, 8, 16, …)
 * and depends on the blur radius, the texture size, among others.
 *
 * The texture is drawn into a downscaled framebuffer; the blur passes are
 * applied on the downscaled texture contents; and finally, the blurred
 * contents are drawn
 * upscaled again.
 *
 * ## Hardware Interpolation
 *
 * This blur implementation cuts down the number of sampling operations by
 * exploiting the hardware interpolation that is performed when sampling between
 * pixel boundaries. This technique is described at:
 *
 * http://rastergrid.com/blog/2010/09/efficient-gaussian-blur-with-linear-sampling/
 *
 * ## Incremental gauss-factor calculation
 *
 * The kernel values for the gaussian kernel are computed incrementally instead
 * of running the expensive calculations multiple times inside the blur shader.
 * The implementation is based on the algorithm presented by K. Turkowski in
 * GPU Gems 3, chapter 40:
 *
 * https://developer.nvidia.com/gpugems/GPUGems3/gpugems3_ch40.html
