It is possible for userspace to create a big object large enough for a 256x256, and then switch over to using it as a 64x64 cursor. This requires the cursor update routines to check for a change in width on every update, rather than just when the cursor is originally enabled. This also fixes an issue with 845g/865g which cannot change the base address of the cursor whilst it is active.
