More drawing tool woes: no mouseDown or mouseUp sent?

[MisterX]

this works...

i made a palette stack whose card script is frontscripted.

all mouse events work... in pointer mode in the normal stack where i would
edit the controls.

the only danger is if you dont check where clicking is legal and where it's
not (if not in the editor stack, pass the events), or you'll be in
click-trouble... ;) Keep the front script open just in case...

That's is how resizeNO2 works to overide teh way Rev resizes controls so you
can have proportional or square shapes and or horizontal, vertical lines... 

The script is open
