Peter Hutterer d36adf52a2 dix: fix WarpPointer calls for devices with custom valuator ranges (#19297) ...

If the MD's lastSlave was a devices with custom axes ranges, then a
WarpPointer would position the cursor at the wrong location. A WarpPointer
request provides screen coordinates and these coordinates were scaled to the
device range before warping.

This patch consists of two parts:
1) in the WarpPointer handling, get the lastSlave and post the event through
   this device.
2) assume that WarpPointer coordinates are always in screen coordinates and
   scale them to device coordinates in GPE before continuing. Note that this
   breaks device-coordinate based XWarpDevicePointer calls (for which the spec
   isn't nailed down yet anyway) until a better solution is found.
