+ * Predictable pointer acceleration
+ *
+ * 2006-2009 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 at runtime.
+ * The classic profile is intended to cleanly perform old-style
+ * function selection (threshold =/!= 0)

+ * miPointerSetCursorPosition

+ * the processing stage. Since we inject the PointerKey events in the
+ * processing stage though, we need to manually reset to restore the
+ * previous order, because the events already in the EQ must be sent for the
+ * right device.
