Add an option to avoid data reprojection ?

[Jul-Git]

Hi,

Thanks a lot for this very helpful application.
Will it be possible to add an option to avoid coordinates reprojection ?

I have a dataset with EPSG4978 coordinates, but when I try to transform it, errors are raised. It seems that the application cannot found any transformation from EPSG4978 to EPSG4978 (which is quit logical, in my point of view). The log is attache below.
Log.txt.

Thanks.
