* IP Address control
*
* Copyright 1998, 1999 Eric Kohl
* Copyright 1998 Alex Priem <alexp@sci.kun.nl>
*
* NOTES
*
* TODO:
* -Check ranges when changing field-focus.
* -Check all notifications/behavior.
* -Optimization: include lpipsi in IPADDRESS_INFO.
* -CurrentFocus: field that has focus at moment of processing.
* -connect Rect32 rcClient.
* -handle right and left arrows correctly. Boring.
* -split GotoNextField in CheckField and GotoNextField.
* -check ipaddress.cpp for missing features.
* -refresh: draw '.' instead of setpixel.
* -handle VK_ESCAPE.
