I really like GTK (but don't use GNOME).  After many years of using the
Intrinsics, I got used to object creation calls all returning Widget*, and all
widget-related functions taking Widget* arguments, leaving the functions to
check for valid subclasses instead of the programmer doing it explicitly.

Though I find some of these differences mildly annoying, these are minor
because GTK is very usable in just about all other respects.

My guess is that the differing return types were done as a matter of
convenience at one point and never quite got fixed to meet policy.
