bugfix: uninitialized pPointer in miPointerGetPosition ifndef MPX adding DeviceIntPtr parameter to ScreenRec's cursor functions. cleanup of miPointer code to use same scheme in each function dix: MPHasCursor() function determines checking whether to invoke cursor rendering. animcur: adding DeviceIntPtr parameter to cursor functions but animcur relies on the core pointer right now. xfixes: adding DeviceIntPtr parameter to cursor functions but xfixes relies on the core pointer right now. rac: adding DeviceIntPtr parameter to cursor functions but RAC relies on the core pointer right now. ramdac: adding DeviceIntPtr parameter to cursor functions but ramdac relies on the core pointer right now.
