[WIN32SS:ENG] Call display mouse functions only when using hardware pointer

Browse Source 
Otherwise, use software pointer functions.

This fixes graphical glitches on cursor change, when the display driver
provides accelerated pointer functions (DrvSetPointerShape/DrvMovePointer),
but refuses to handle a certain cursor.

These graphical glitches may be reproduced:
- by using Voodoo driver SFFT 1.9
- by using framebuf_new.dll instead of framebuf.dll
- by using the panning driver (setting DefaultSettings.XPanning and
  DefaultSettings.YPanning in registry)
