this is a version of d3dex1 that demonstrates how a windowed direct draw
app can/should handle multiple monitors.
files:
d3dex2.cpp - about the same as the original d3dex1
look at how this app uses the routines
in ddmm.cpp
look at how this app handles WM_MOVE to
detect when the window moves monitors.
look at how it converts from a window
client cordinate to a device cordinate
ddmm.cpp - generic directdraw multimonitor helper routines.
DirectDrawCreateFromDevice
DirectDrawCreateFromWindow
DirectDrawDeviceFromWindow
multimon.h - stub multimon functions that use GetProcAddress
used by ddmm.cpp, so it can still run on
Win95 or NT4
