Sets a specific GdkCursor for a given device when it gets inside window.
Use gdk_cursor_new_for_display() or gdk_cursor_new_from_pixbuf() to create
the cursor. To make the cursor invisible, use GDK_BLANK_CURSOR. Passing
NULL for the cursor argument to gdk_window_set_cursor() means that
window will use the cursor of its parent window. Most windows should
use this default.
