Yes, it has--see for example the bottom drawer in the DrawerMadness
example.  It uses the method you already hit on, of adjusting
leading/trailing offsets in windowDidResize:.  I suspect you are
correct about your problem being due to your resize increments.  I
would suggest you try controlling the parent window size yourself in
windowWillResize:toSize:, rather than using resize increments, and then
adjusting the drawer offsets in windowDidResize:.
