/*
hspPlayAVI -- allocates a movieinfo structure, stores the window
handle you gave it in the hwndParent entry in the movieinfo,
and stores the callback you provide in the movieinfo -- these will
be used by the subclassproc.
It next calls InitHotspots to get a hotspot list, and
fileOpenMovie which will open the AVI file and create a child
window (a child of the window that you pass in to this function).
The window is returned in the movieinfo. It then subclasses
the window fileOpenMovie made, by changing the pointer to its
WindowProc to ours (via SetWindowLong).
It uses SetProp to hook this movieinfo up to both windows.
The subclassed wndproc will get the movieinfo from the child
window when a button is clicked, and the parent windowproc will
get the movieinfo from the parent when Viewer wants to know
the pane size.
Finally, playMovie is called to start the movie.
