Sets a specific gdk.Cursor for a given device when it gets inside window.
Use Cursor.newForDisplay or Cursor.newFromPixbuf to create
the cursor. To make the cursor invisible, use GDK_BLANK_CURSOR. Passing
NULL for the cursor argument to Window.setCursor means that
window will use the cursor of its parent window. Most windows should
use this default.
