window: Update drag hotspot as new touches approach

Any number of touches >= 3 starts a drag operation, but the window jumped around as new touches joined. So recalculate the touch drag area/hotspot and tiling mode as expected as soon as touches enter/leave the drag op.
window: Implement tiling/maximizing through touch events

+
+2.91.3
+======
+
+* Better shadows: [Owen]
+   - Shadows can be different for different window types and focus states
+   - Shadows are larger by default, especially for the currently active
+     window
+   - Shadows for attached modal dialogs and menus are drawn not to
+     overlap the attachment point.
+   - Shadows follow the shape of shaped windows
+ * Optimization: [Owen]
+   - Avoid repainting in situations when windows are potentially restacked
+     but aren't actually restacked.
+   - Pay attention to partial stage repaints in obscured window calculations
+   - Better optimization of painting obscured shadows; turn off shadows
+     for maximized windows.
+   - Move background repainting into Mutter; doing it here rather than
+     in plugins allows not painting obscured parts of the background.
+ * A new frame type 'attached' is added for attached modal dialogs
+   and can be referenced in theme files with a theme version of 3.2.
+ * Fix updating key bindings when the keyboard layout changes

+    mutter_get_windows        => meta_get_window_actors
+    mutter_plugin_get_windows => meta_plugin_get_window_actors
+* Add missing values in MetaKeyBindingAction - this fixes a problem where
+  key binding lookup wasn't working properly for some key bindings. [Dan]
+* Remove keysym parameter to meta_display_get_keybinding_action() - the
+  function expected the default keysym for the keycode to always be passed [Dan]
+* Clean up installed header files - in particular, theme-parser.h is merged
+  into a new public-only theme.h and private internals are moved to
+  theme-private.h.
+* Fix problems with antialiased rendering of themes [Brandon, Owen, Nickolas]

+New Features in Theme Format Version 3.4
+========================================
+
+An additional color type is added to pick up custom colors defined
+in the GTK+ theme's CSS:
+
+  gtk:custom(name,fallback)
+
+where <name> refers to a custom color defined with @define-color in
+the GTK+ theme, and <fallback> provides an alternative color definition
+in case the color referenced by <name> is not found.

  <shortdesc xml:lang="en">Window and compositing manager based on Clutter</shortdesc>
+  <description>Mutter is a window and compositing manager that displays and
+manages your desktop via OpenGL. Mutter combines a sophisticated display engine
+using the Clutter toolkit with solid window-management logic inherited from the
+Metacity window manager.
+
+While Mutter can be used stand-alone, it is primarily intended to be used as
+the display core of a larger system such as GNOME Shell. For this reason,
+Mutter is very extensible via plugins, which are used both to add fancy visual
+effects and to rework the window management behaviors to meet the needs of the
+environment.</description>

-Plugins implement effects associated with WM events, such as window map,
-minimizing, maximizing, unmaximizing, destruction and workspace switching. The
-plugin API is documented in src/include/compositor-clutter-plugin.h; in
-addition the simple plugin can be used as a reference implementation.
-
-The API is intended to be generic, exposing no implementation details of the WM
-to the plugins; this will facilitate reuse without modification with another WM
-(there are plans to use the same plugin API with Matchbox 2).
-
-Multiple plugins can implement the same effect and be loaded at the same time;
-however, stacking arbitrary effects in this way might not work as expected;
-this is particularly true of more complex effects, such as those for workspace
-switching.
-
-Plugins are installed in ${prefix}/lib/metacity/plugins/clutter; from there the
-WM will load plugins listed in the clutter_plugins key in the Metacity gconf
-general preferences group. Each entry in preferences has the format
-
-  'name: optional parameters'
-
-where 'name' is the name of the library without the .so suffix.
-
-As noted above, additional parameters can be passed to the plugin via the
-preference key. In such case, the plugin name is immediately followed by a
-colon, separating it from the parameters. Two common parameters should be
-handled by all plugins:
-
-  'debug'   indicates that the plugin is run in a debug mode (what exactly that
-            means is left to the plugin to determine).
-
-  'disable' parameter indicates which effects within the plugin should be
-            disabled; the format of the disable parameter is
-
-              'disable: effect1[, effect2];'
-
-            where effect1, etc., matches the effects listed in the
-            compositor-clutter-plugin.h file (currently one of 'map', 'destroy',
-            'maximize', 'unmaximize', 'switch-workspace'). Example 'disable:
