DocStr(wxCursor,
"A cursor is a small bitmap usually used for denoting where the mouse
pointer is, with a picture that might indicate the interpretation of a
mouse click.

A single cursor object may be used in many windows (any subwindow
type). The wxWindows convention is to set the cursor for a window, as
in X, rather than to set it globally as in MS Windows, although a
global `wx.SetCursor` function is also available for use on MS Windows.
