Apparently there are two kinds of "owner draw" buttons in Windows 3.0.
Petzold documents the BS_USERBUTTON style but not the BS_OWNERDRAW
style.  The SDK documentation describes the BS_OWNERDRAW style but
not the BS_USERBUTTON style.  The BS_USERBUTTON style seems slightly
less functional.

I'm new to Windows programming, but my guess is that the BS_USERBUTTON
style was present in earlier releases of Windows and has been superceded
by the BS_OWNERDRAW style.  Am I right?  Does anybody know some history
behind the two styles?  More importantly, is there any reason to prefer
the BS_OWNERDRAW style if the BS_USERBUTTON style provides sufficient
functionality?  Known bugs, etc.?
