What is the semantic of WSDISPLAYIO_SCURSOR ioctl?  No man page even
mentions it.  In particular what is the semantic of 'image' and 'mask'
fields of struct wsdisplay_cursor?

Shall software assume less then 256 colors cmap and pass image/mask as
u_char per pixel, or should it query cmap size first with
WSDISPLAYIO_GCURSOR/WSDISPLAY_CURSOR_DOCMAP and pack the cursor pixmap
appropriately?

PS: Grepping through the tree it seems that only alpha's framebuffers
and arm's vidcvideo and vax' smg implement this ioctl.  By chance,
does authors of those drivers has any code to test the feature?

SY, Uwe
