* Copyright 1998 Eric Kohl
*
* TODO:
* - Tracking tooltips (finished, except smart placement).
* - Transparent tooltips (under construction).
* - TTS_ALWAYSTIP (undefined).
* - Unicode support.
* - Custom draw support.
* - The "lParam" variable from NMTTDISPINFO32A is not handled
* in TOOLTIPS_GetTipText.
*
* Testing:
* - Run tests using Waite Group Windows95 API Bible Volume 2.
