/****************************************************************************
Freecell.c
June 91, JimH initial code
Oct 91, JimH port to Win32
Main source module for Windows Free Cell.
Contains WinMain, initialization routines, and MainWndProc.
Design notes:
Note that although this program uses some of the mapping macros,
this version of the code is 32 bit only! See Wep2 sources for
16 bit sources.
The current layout of the cards is kept in the array card[MAXCOL][MAXPOS].
In this scheme, column 0 is actually the top row. In this "column", pos
0 to 3 are the free cells, and 4 to 7 are the home cells. The other
columns numbered 1 to 8 are the stacked card columns.
See PaintMainWindow() for some details on changing the display for EGA.
A previous version of Free Cell used a timer for multi-card moves.
WM_FAKETIMER messages are now sent manually to accomplish the same thing.
