    I'm porting an editor from Gold-Hill CL to CLIM 1.0 on MCL 2.0 (both beta).
    When drawing in Gold Hill (MS-Windows) text can overwrite other text, instead
    of combining with it. How can I specify a boolean function over destination
    and source pixels or getting the same effect, in CLIM? I read about
    compose-in and -out but didn't understand it well enough to be able to use
    them.

    If I get the help I need I may release it for public use...so please help.

This is a deficiency in CLIM.  Right now, it does not provide a simple
way to do this.  You should explicitly erase the region you plan to
overwrite before drawing on it; DRAW-RECTANGLE* will suffice for this.
