// Project: ItsyBitsy window support module
// Module: itsybits.c
//
//
// ItsyBitsy is a support module that allows you to create windows
// that look and act very much like a popup window witha system
// menu and caption bar, except everything is scaled to about 2/3
// scale.
//
// For documentation on how to use ItsyBits, read the document
// ITSYBITS.DOC.
//
// Revisions:
// 9/27/91 Charlie Kindel (cek/ckindel)
// Wrote and documented it.
//
// 1/14/93 cek
// 2/23/93 cek Added minimize/maximize buttons.
// 3/18/93 cek Fixed system menu bug where system menu
// popped back up if you clicked on the
// icon again while it was up.
// 3/24/93 cek More comments. Fixed DS_MODALDIALOG style
// problem. Use auto precompiled headers
// in MSVC.
