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)
