/****************************************************************************
* PROJECT: Squeak port for Win32 (NT / Win95)
* FILE: sqWin32Window.c
* CONTENT: Window management
*
* AUTHOR: Andreas Raab (ar)
* ADDRESS: University of Magdeburg, Germany
* EMAIL: raab@isg.cs.uni-magdeburg.de
*
* NOTES:
* 1) Currently supported Squeak color depths include 1,4,8,16,32 bits
* 2) To speed up drawing a slight update delay has been added (Toggle with F2)
* 3) The modifier keys are mapped as follows:
*
* Mac | Win32
* --------------------
* Shift -> Shift
* Ctrl -> Ctrl
* Command -> Left ALT
* Option -> Right ALT
