Subject: [PATCH] MeshTools: allow views to be passed to the transform*()
 functions.

Before, the functions didn't accept a r-value view. Now they do, and
they also still accept l-values.

However, for a proper thing I should be making those non-templated,
specialized for Float and Double and implemented using SIMD. Well,
later.
