Is there a way to get ALL the polygon's UVids at once?

The documentation suggests that this data exists somewhere internally but there's no way to get it.

The structure that holds UVs in Maya consists of two arrays:

A UV index array that uses the exact same indices of the face array (visualized as a face vertex array).
A UV array that holds a list of UV points indexed by UVIds.

The currently available api methods (that I'm aware of) queries faceVtx individually and are simply too slow on a large mesh. Especially when doing this via Swig/ API2
