Corrected the problem of saving the imported KROKI project to the same
file from which it was imported. Corrected an error in import noticed
when trying to start the imported KROKI diagram as a desktop
application.
Changed the code that determines the state of the canvas that shows the
Standard form, because it did not always set the Resize state when the
cursor was on the handles for resizing a Standard form.
Changed the predefined height of the canvas that shows the Standard
form.
