[Gmsh] Problem with 2D plots

[JP Moitinho de Almeida]

We are obtaining incorrect 2D plots, with user defined 
InterpolationSchemes and ElementNodeData.

This was reduced to the attached example.

Just open the simple.script file in gmsh and the two plots illustrate 
the problem. The difference between the two data sets is that one has 
rounding errors (the bad) and the other (the good) does not.

I looked at the code for the adaptiveLine class, but was not able to 
quickly understand what may be missing.

Is there an obvious fix (or a mistake on  our side)?

Regards

ZP
