Extend intermediateTo to support any number as a fraction

[naktinis]

Not sure what your opinion is about extending intermediateTo (which this issue was about). For some reason we were only discussing alongTrackDistanceTo.

[mrJean1]

My apologies, I clicked the wrong issue, twice. The name intermediateTo (and intermediatePointTo) and the comments in the JS code implied that only factor values 0..1 were suitable. But the JS code puts no restriction on the factor value, I'd be happy to do that in the Python version.

[naktinis]

Completely agree about naming.

[mrJean1]

Good. There are 3 spherical intermediate... methods and the fraction restriction is being removed for all, just to be consistent.

[mrJean1]

All done in PyGeodesy-17.4.28 plus some other modifications.

[naktinis]

Are there any tests for fractions outside 0..1? I think h computation does not work for such values. Otherwise it looks ok.

[mrJean1]

No tests, but I'll check with the original author. Also, I'll add a height keyword. If not None, it will replace the fractional default.

[mrJean1]

A keyword argument height=None has been added to all intermediate...To and several other methods to override the computed, default or fractional height value in PyGeodesy-17.5.01+. There are other updates as well, including 2 simplistic tests for spherical and ellipsoidal intermediateTo methods with fraction values outside 0..1.

@naktinis, has this been resolved to your satisfaction?

[naktinis]

Seems to work as expected. Thank you.
