IIRC, the control is hierarchical. For example, if you have a three deep
hierarchy of external references like this:
file A --- palette, override file B.

file B --- no palette, inherit file A palette, override on file C.

file C --- palette, inherit file B palette.
... then file C inherits file A's palette because that is the effective
palette for file B.

The fallback for a truely missing palette is for a file to use its own
palette. Failing that it really is then undefined behavior depending on
the palette in question (e.g. color is white, texture is null)
