Description
Possibly we can more easily support varying scales (e.g., parcoords and sploms) by passing scaled channels to marks, instead of having the marks invoke the scale, or by passing a function that takes an index.

Research direction
No files or tests are named. Start by reviewing how scales and marks currently handle channels, then examine the parallel-coordinates and SPLOM cases. Compare the proposed scaled-channel and index-based-function approaches, and define the desired behavior for multiple x- or y-scales before implementation.
