Why would you need to loop through all existing cords?... I don't 
understand.

You need to perform only one check per canvas. Basically, if 
glist==glist_getcanvas(glist), then a canvas' cords are visible when the 
canvas itself is visible, and if this pd canvas also has a tk canvas, then 
it can tell the tk canvas to raise all_cords and that's all. You don't 
need an explicit loop and you don't benefit from one.

(unless someone found a speed optimisation in the use of tk, but then, it 
would involve more checks than what we're talking about here, and more 
accounting in order to avoid unnecessary refreshes, etc)
