There is no way to "force" an allocation, you must be prepared to
handle any allocation without crashing (though you might not be able
to display properly).

The right solution is just to pack your widget in containers such that
it gets its size request and not some other size. Normally this means
having "expand" and "fill" parameters turned off. I wouldn't solve
this problem by changing the widget itself (any more than you would
solve the problem of a huge distorted GtkButton by changing
GtkButton).
