ptc wndproc example
-------------------

This example demonstrates how to use a custom WndProc with PTC.

It loads an image, but doesnt display it immediately. Mouse events are handled
so that the image is revealed as the user drags the mouse across the window 
with the left button pressed.

This example will only operate under Win32.

to compile the example use the batch files provided:

    eg. "wc11 windows"    (compile with watcom c++ 11.0)
        "vc5x windows"    (compile with visual c++ 5.x)

note: the batch files make a debug executable by default. you can gain
significant speed by building a release executable. for more information 
read the remarks in the batch files.
