cursor - change the current mouse cursor

cursor ?options?

Cursor changes the image displayed at the current mouse position. The following options are supported:

-image image
Image gives a name created using the image (9) command; the image must conform to the rules given for Display.cursor (see draw-display (2)).
-bitmap bitmap
Similar to -image but using the bitmap syntax (see types (9)).
-x dist
The cursor will be drawn dist to the right of the actual position of the mouse.
-y dist
The cursor will be drawn dist below the actual position of the mouse.
Revert the cursor to its default image.

A cursor image should have some inherent association with its hot-spot offset.
