Make script flow visualisations work regardless of flow pattern (size).

[a-t-0]

Currently the script flow works hardcoded for vertical size of 1 and 2, as explained here, however for screen flows with 3 vertical screens, the rendering does not work.

I tried changing the figure size and the vertical positions of the 3 images, however that did not result in a vertical spacing between the 3 vertical screens. Even when changing the aspect ratio of the image. An option could perhaps be to:

• increase the figure size, and/or aspect ratio based on the screen image size and nr of vertical levels.
• Lower the screen image size in the piesize = 0.4 # this is the image size parameter.
  such that the images become relatively smaller in the figure, but that the figure becomes larger, yielding the same DPI per image.
