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.
