-The following changes have been made to this directory since R3 (for
-a full description, see doc/Server/r4.tbl.ms):
-
- o Windows restructured (memory reduction, devPrivates and speedups)
- o GCs restructured (memory reduction, devPrivates and wrappers)
- o Screens restructured (window ops merged in, devPrivates)
- o Pixmaps restructured (drawable changes mostly)
- o Cursors restructured (shares glyph bits now)
- o Visuals restructured (screen index removed, fields rearranged)
- o Devices restructured (input extension changes)
- o Out of memory changes. Many interfaces now return OutOfMemory
- status.
- o Synchronous grab code rewritten. Should conform to our
- understanding of the protocol now. Be careful when time
- stamping events (don't allow time to run backwards).
- o Resource types redesigned and rewritten.
- o Internal fake color allocation routine for software cursors.

+ * focus in/out in the case of multiple pointers/keyboard foci
+ * Since we can't send more than one Enter or Leave/Focus in or out event per
+ * window to a core client without confusing it, this is a rather complicated
+ * approach.
+ *
+ * For a full description of the enter/leave model from a window's
+ * perspective, see
+ * http://lists.freedesktop.org/archives/xorg/2008-August/037606.html
+ *
+ * For a full description of the focus in/out model from a window's
+ * perspective, see
+ * http://lists.freedesktop.org/archives/xorg/2008-December/041740.html
+ *
+ * Additional notes:
+ * -) The core protocol spec says that "In a LeaveNotify event, if a child of the
+ * event window contains the initial position of the pointer, then the child
+ * component is set to that child. Otherwise, it is None. For an EnterNotify
+ * event, if a child of the event window contains the final pointer position,
+ * then the child component is set to that child. Otherwise, it is None."
+ *
+ * By inference, this means that only NotifyVirtual or NotifyNonlinearVirtual
+ * events may have a subwindow set to other than None.
+ *
+ * -) NotifyPointer events may be sent if the focus changes from window A to
+ * B. The assumption used in this model is that NotifyPointer events are only
+ * sent for the pointer paired with the keyboard that is involved in the focus
+ * events. For example, if F(W) changes because of keyboard 2, then
+ * NotifyPointer events are only sent for pointer 2.

+ * Predictable pointer acceleration
+ *
+ * 2006-2008 by Simon Thum (simon [dot] thum [at] gmx de)
+ *
+ * Serves 3 complementary functions:
+ * 1) provide a sophisticated ballistic velocity estimate to improve
+ * the relation between velocity (of the device) and acceleration
+ * 2) make arbitrary acceleration profiles possible
+ * 3) decelerate by two means (constant and adaptive) if enabled
+ *
+ * Important concepts are the
+ *
+ * - Scheme
+ * which selects the basic algorithm
+ * (see devices.c/InitPointerAccelerationScheme)
+ * - Profile
+ * which returns an acceleration
+ * for a given velocity
+ *
+ * The profile can be selected by the user (potentially at runtime).
+ * the classic profile is intended to cleanly perform old-style
