Detail:
  This set of changes adds support for rendering software mouse pointers directly in the kernel, rather than requiring graphics drivers to render them themselves as was the case previously.
  If a driver returns from GraphicsV_Features with the 'hardware pointer' bit clear, and a call to GraphicsV_UpdatePointer is returned unclaimed, then the kernel will step in and render a software pointer. This allows selective control over which areas of the screen the software pointer is used (e.g. if hardware only supports its use in some areas)
  hdr/KernelWS - Shrink PointerXEigFactor to 1 byte to free up some space for tracking the display log2bpp. Use 8 words of space for tracking software pointer state.
  s/vdu/vducursoft - Adjust existing the existing calls to the software pointer RemovePointer/RestorePointer functions so that they're called with IRQs enabled
  s/vdu/vdudriver - Keep track of display log2bpp. Claim/release memory needed for restoring pixels under so...
