More similarity in the usage of Axis() and Axis3()

[tduretz]

Here are some idea that popped when making figures with both Axis() and Axis3()

1. The data aspect:
   To make sure no exaggeration is applied to a direction using Axis() one should do:
   Axis(aspect = DataAspect(), ...)
   while for Axis3, on should type:
   Axis3(aspect = :data, ...)
   Would there be a way to homogenise this? As such, I find it a bit confusing and I always mix them up :D
2. The default mouse interactions:
   With Axis() it is straightforward to zoom and pan.
   With Axis3(), it's easy to rotate but it would be great to be able to zoom and pan as with Axis() (I could imagine it's probably not a simple thing to implement?)

and thanks for this excellent visualisation package, cheers!
