1.2.0

New Features

• Survex .3d Bv0.01 format supported.
• Approximate station depth below surface shown in station info popup, when a terrain is available.

Bug Fixes

• File extension checking now case insensitive.
• Survex files containing stations with names including the '.' separator handled correctly (surveys now load)
• Station lists not sorted in the UI when an excessive number of stations would cause large pauses if sorted when displaying the survey structure page, or changing shading methods.
