Sets the window's cursor. Notice that setting the cursor for this window also
sets it for all the children of the window unless they have their own cursor
(either explicitly set with the same function, or, in the case of Windows, a

Sets the window's cursor. Notice that setting the cursor for this window does
not set it for its children so you'll need to explicitly call SetCursor() for
them too if you need it.
