the visible of a stack

[Chipp Walters]

Typo.. blendlevel is spelled with an 'L' at the end.

function isStackCurrentlyVisibleOnAnyMonitor pStack
  --> pStack IS THE SHORT NAME OF STACK
  set wholematches to true
  if pStack is among the lines of windows() then
     if the blendlevel of stack pStack = 100 then return false
     repeat for each line L in the screenrects
        if the topLeft of stack pStack is within L then return true
        if the bottomright of stack pStack is within L then return true
     end repeat
     return false
  else
     return false
  end if
end isStackCurrentlyVisibleOnAnyMonitor
