If you're drawing `custom' objects in your dialog box that can't be managed
with the given set of boxes, buttons, etc, you should consider using a
G_PROGDEF object: the ob_spec should then point at a data structure (can't
remember the name) which contains the address of a routine to do the custom
drawing, and a longword parameter.  This way you can still use objc_draw(), 
which will automatically use your code to draw your custom object.  Again, I
would recommend Tim Oren's ProGEM for a better explanation of this.
