Track only motion

The fact that the buttons right above the touchpad actually report
events for the trackpoint puts a wrench into the current device
tracking idea. I always use those buttons together with the touchpad,
so I constantly change the current device between touchpad and
trackpoint, which ruins the experience.

To overcome this problem, use only motion events for the current
tracking, eliminating the problem, but making this tracking less
generally useful. It is really tailored towards overlay scrolling
now.

+Overview of Changes in GTK+ 3.15.0
+==================================
+
+* GDK supports rendering windows using OpenGL; currently
+  this is implemented for X11 and Wayland using libepoxy
+
+* GtkGLArea: A new widget for rendering with OpenGL
+
+* GtkSidebar: A new switcher for GtkStack that looks like
+  a sidebar
+
+* Better typography: In many places, we now use proper Unicode
+  characters for dashes, quotes, multiplication signs and the
+  like, instead of ASCII approximations
+
+* Theming:
+ - Context menus use the default font instead of inheriting from
+   the widget they are attached to
+ - Theming engines are no longer used
+ - Backdrop style has been fine-tuned to make the difference to
+   the active window more evident without affecting readability
+
+* Inspector:
+ - Show nested tree models
+ - Add a checkbox to disable the warning dialog
+ - Rearrange the UI to gain space
+ - Show object counts
+
+* GtkTextView has a monospace property
+
+* GtkPaned has a wide-handle property
+
+* GtkPrintUnixDialog
+ - Has improved appearance without headerbars
+ - Better rendering of sheet icons
+ - No more missing icons
+
+* GtkScrolledWindow
+ - A new policy, GTK_POLICY_EXTERNAL, which allows scrolling
+   without showing a scrollbar
+ - Scroll events can now overshoot as well
+ - The new signal ::edge-overshot is emitted when the scrolled
+   window is fully overshot
+ - Scrollbars will be overlayed as narrow indicators when
+   there is no mouse

 from a specific GLib source tree.
 
+Please note, as GTK+ uses the Adwaita theme for all platforms by default,
+most icons used are not included with GTK+ (which *are* needed), so please see
+https://live.gnome.org/GTK%2B/Win32/MSVCCompilationOfGTKStack (under the
+GTK+ section) on how to get those icons set up for use with GTK+.
+
 *About the dependencies marked with *: These dependencies are optional
  as those are not compulsory components for building and running GTK+
  itself, but note that they are needed for people running and building

+ * SECTION:gdkglcontext
+ * @Title: GdkGLContext
+ * @Short_description: OpenGL context
+ *
+ * #GdkGLContext is an object representing the platform-specific
+ * OpenGL drawing context.
+ *
+ * #GdkGLContexts are created for a #GdkWindow using
+ * gdk_window_create_gl_context(), and the context will match
+ * the #GdkVisual of the window.
+ *
+ * A #GdkGLContext is not tied to any particular normal framebuffer.
+ * For instance, it cannot draw to the #GdkWindow back buffer. The GDK
+ * repaint system is in full control of the painting to that. Instead,
+ * you can create render buffers or textures and use gdk_cairo_draw_from_gl()
+ * in the draw function of your widget to draw them. Then GDK will handle
+ * the integration of your rendering with that of other widgets.
+ *
+ * Support for #GdkGLContext is platform-specific, context creation
+ * can fail, returning %NULL context.
+ *
+ * A #GdkGLContext has to be made "current" in order to start using
+ * it, otherwise any OpenGL call will be ignored.
+ *
+ * ## Creating a new OpenGL context ##
+ *
+ * In order to create a new #GdkGLContext instance you need a
+ * #GdkWindow, which you typically get during the realize call
+ * of a widget.
+ *
+ * ## Using a GdkGLContext ##
+ *
+ * You will need to make the #GdkGLContext the current context
+ * before issuing OpenGL calls; the system sends OpenGL commands to
+ * whichever context is current. It is possible to have multiple
+ * contexts, so you always need to ensure that the one which you
+ * want to draw with is the current one before issuing commands:
+ *
+ * |[<!-- language="C" -->
+ *   gdk_gl_context_make_current (context);
+ * ]|
+ *
+ * You can now perform your drawing using OpenGL commands.
+ *
+ * You can check which #GdkGLContext is the current one by using
+ * gdk_gl_context_get_current(); you can also unset any #GdkGLContext
+ * that is currently set by calling gdk_gl_context_clear_current().

+  /* The paint logic here is a bit complex because of our intermingling of
+   * cairo and GL. Let's first go over the cairo-alone case:
+   *
+   *  1) gdk_window_begin_paint_region() is called with an update region. If
+   *     the backend wants it, we redirect drawing to a temporary surface
+   *     sized the same as the update region and set `surface_needs_composite`
+   *     to TRUE. Otherwise, we paint directly onto the real server-side window.
+   *
+   *  2) Things paint with cairo using gdk_cairo_create().
+   *
+   *  3) When everything is painted, the user calls gdk_window_end_paint().
+   *     If there was a temporary surface, this is composited back onto the
+   *     real backing surface in the appropriate places.
+   *
+   * This is similar to double buffering, except we only have partial surfaces
+   * of undefined contents, and instead of swapping between two buffers, we
+   * create a new temporary buffer every time.
+   *
+   * When we add GL to the mix, we have this instead:
+   *
+   *  1) gdk_window_begin_paint_region() is called with an update region like
+   *     before. We always redirect cairo drawing to a temporary surface when
+   *     GL is enabled.
+   *
+   *  2) Things paint with cairo using gdk_cairo_create(). Whenever
+   *     something paints, it calls gdk_window_mark_paint_from_clip() to mark
+   *     which regions it has painted in software. We'll learn what this does
+   *     soon.
+   *
+   *  3) Something paints with GL and uses gdk_cairo_draw_from_gl() to
+   *     composite back into the scene. We paint this onto the backing
+   *     store for the window *immediately* by using GL, rather than
+   *     painting to the temporary surface, and keep track of the area that
+   *     we've painted in `flushed_region`.
+   *
+   *  4) Something paints using software again. It calls
+   *     gdk_window_mark_paint_from_clip(), which subtracts the region it
+   *     has painted from `flushed_region` and adds the region to
+   *     `needs_blended_region`.
+   *
+   *  5) Something paints using GL again, using gdk_cairo_draw_from_gl().
+   *     It paints directly to the backing store, removes the region it
+   *     painted from `needs_blended_region`, and adds to `flushed_region`.
+   *
+   *  6) gdk_window_end_paint() is called. It composites the temporary surface
+   *     back to the window, using GL, except it doesn't bother copying
+   *     `flushed_region`, and when it paints `needs_blended_region`, it also
+   *     turns on GL blending.
+   *
+   * That means that at any point in time, we have three regions:
+   *
+   *   * `region` - This is the original invalidated region and is never
+   *     touched.
+   *
+   *   * `flushed_region` - This is the portion of `region` that has GL
+   *     contents that have been painted directly to the window, and
+   *     doesn't have any cairo drawing painted over it.
+   *
+   *   * `needs_blended_region` - This is the portion of `region` that
+   *     GL contents that have part cairo drawing painted over it.
+   *     gdk_window_end_paint() will draw this region using blending.
+   *
+   * `flushed_region` and `needs_blended_region` never intersect, and the
+   * rest of `region` that isn't covered by either is the "opaque region",
+   * which is any area of cairo drawing that didn't ever intersect with GL.
