Unknown Term

[Richmond Mathewson]

dropFile

as in:

on mouseUp
  answer file "Please choose an image:"
  if it is not empty then
    dropFile it
  end if
end mouseUp

in the 'Core Image Visual Effects' stack.

Could find no reference to this term in either the built-in
documentation or the PDF.

As this code appears exactly the same in a number
of buttons it is not at all clear where the reference to
the source file goes.
