Unfortunately, IDL does not have the relatively comprehensive support
for coordinate systems and plot methods that one finds, for example,
in Mathematica. I attribute this (perhaps erroneously) to the fact that
the dominant legacy in IDL is image processing, rather than applied
math and mathematical physics.

Given the (lack of) interest from ITTVIS in direct graphics, this is
unlikely to change, in that domain at least.

Streamlines pose some real challenges, but vector plotting support
should be much better than it is (in my opinion), especially when
it comes to plotting vectors on maps.
