Sylvian,

The code in question is intended to preserve "aspect ratio" of pixels while
your changes allow a fit_extents call to alter the aspect ratio of the view.
While you are welcome to have the changes in your copy, I am not going to
incorporate them in core at this time since preservation of aspect ratio is
a fundamental requirement of the primary users of OpenEV.

If there is wider demand, I could possible change the code to be control
whether aspect ratio is retained based on a runtime flag but without more
desire for the change I am more worried about the risk of messing up existing
code.

You are also correct in suspecting that more appropriate local projections
would give better planimetric display of the S-57 data.

Best regards,
