    ### KLUGE: without the pixelgap adjustment (to this particular weird-looking value, i guess),
    # the label moves to the right when highlighted, due to the Boxed being used to position it in the row.
    ### BUG: CenterY is not perfectly working. Guess -- lbox for TextRect is slightly wrong.
    ### IDEA: make the borderthickness for Boxed negative so the border is over the edge of the plain button. Might look better.

    # and then have ordinarily-drawn pressed etc looks. [070227 comment]

            # I don't have a theory for 'if 1' bug cause, or for why it only affects the inner thing, not outer one.
            # Does it only affect that after it's once been hidden? ### if so, is it "you were selobj and then not drawn" that makes it
            # happen? that might fit the data but I don't see how that could work.
            # So I added a 2nd 0.5 so neither gray rect form covers the other. but first inner close hits the bug of making it
            # inactive and act non-highlighted. so i wondered if the glname really only covers the openclose? code says so.

            # reasoning, so plan to add debug prints to glpane. Need to think thru its assumptions re chaotic glname/selobj/size/
            # whether-drawn situation, see which are wrong, which might cause the bug. Also - can event processing occur during
            # paintGL? I hope not, but verify. Also maybe GLPane needs to track frame numbers for selobjs being drawn,
            # stencil bits being made, vs selobj state mods as tracked by inval....
            #
            # update 061121 953a, where I am: after basic fixes elsewhere [some stateplaces not tracked, some usage tracking disallowed],
            # and still using all kluge/workarounds from 061120, bug seems totally fixed for if 0 case, all or most for if 1 ##k.
            # IIRC it was slightly remaining before some usage tracking disallowed, but that is not complaining, which is suspicious.
            # Anyway, if if 1 works too, plan is to gradually remove the kluges and clean up and keep it working.
            # BUT it looks like if 1 (using reloaded code) has a bug of some disallowed usage... details to follow.
            # BUT after restart I don't see it. BTW I recently reenabled reloading -- could that have fixed some bugs (how???),
            # or could it be that they now occur after reloading but not before it?? indeed, this is after changing if 1->0 and reload,
            # and looks like it might relate to old state being there, and
            ###### WHAT IF RELOADED CODE USES THE SAME STATE DIFFERENTLY AND HAS A BUG? #####
