+ * miPointerConstrainCursor
+ * miPointerCursorLimits
+ * miPointerDisplayCursor
+ * miPointerRealizeCursor
+ * miPointerUnrealizeCursor
+ * miPointerSetCursorPosition
+ * miRecolorCursor
+ * miPointerDeviceInitialize

+ * If wrapped, these are the last element in the wrapping chain. They may
+ * call into sprite-specific code through further function pointers though.
