 The default is wxCOPY, which simply draws with the current colour.
 The others combine the current colour and the background using a
-logical operation.  wxXOR is commonly used for drawing rubber bands or
+logical operation.  wxINVERT is commonly used for drawing rubber bands or
 moving outlines, since drawing twice reverts to the original colour.
