set-cursor in editor<%>
Sets a custom cursor for the editor. If the custom cursor is
#f, the current cursor is removed, and a cursor is selected
automatically by the editor (depending on whether the cursor is
pointing at a clickback). See
adjust-cursor for more information about the default selection.
An embedding editor's custom cursor can override the cursor of an embedded editor -- even if the embedded editor has the caret -- if the cursor is specified as an overriding cursor.

Sets the custom cursor for the editor to cursor. If
override? is a true value and cursor is not #f,
then this cursor overrides cursor settings in embedded editors.
