Swap call pattern of ArrayHandle::DeepCopy
The new method ArrayHandle::DeepCopy
had the pattern such that the
data in the this
array was pushed to the provided destination array.
However, this is the opposite pattern used in the equivalent method in
VTK, which takes the data from the provided array and copies it to
this
array.
So, swap the pattern to match that of VTK. Also, make the method name
more descriptive by renaming it to DeepCopyFrom
. Hopefully, users will
read that to mean given the ArrayHandle
, you copy data from the other
provided ArrayHandle
.
