Operation: foreach image in list do
The user sets up a list of image filenames. "foreach image in list do" and
"foreach image end" build a loop. In each cycle the result of "foreach
image do" is the current filename. When "foreach image end" is reached
the current filename is set to the next in the list and the execution
continues after "foreach image do". When the last filename in the list
is reached execution continues after "foreach image end". The user sets up the file list using the list editor.
Options

image list: Pressing "edit" openes the list
editor that allows to add and remove images from the list. When a
folder is added all images in the folder and in all subfolders are
added.

If checked the sequence opener is used instead of the file dialog to
select the files. This is preferable when there are many files in a
folder on a windows system.

Results
The operation has three results:
- current filename:
The current filename as a String.
- at end:
A Boolean that tells whether the last image filename in the list has
been reached.
- do operation:
This is the operation itself. This result is needed by the "foreach
image end" operation to determine where to continue execution.
