In DX, a delayed color dataset often has "unsigned byte" colors
ref'ing a "float[256][3]" color map. DX of course renders images of this
sort with no problem, as ReadImage creates them.
However, Import refuses to load such a field (even one created by
ReadImage->Export), reporting:
----------------------------------------------------------------------
ERROR: 38::/Import:0: Invalid data: `colors' component must be
type INT to `ref' another component / file
'power-button.dx' line 23
----------------------------------------------------------------------
Does anyone have a preference for what list of types should allowed to
"ref" another component in addition to TYPE_INT and TYPE_UBYTE
(e.g. TYPE_BYTE, TYPE_SHORT, TYPE_USHORT).
The check is at edfio.c:212. It would need to change along with the
probe code below it. Anyone have a feel whether other areas break as well?
FWIW when I hit this I was writing a colormapped volume (byte voxels)
format converter to DX native, trying to mimick what DX does.

dx> Export(data, "power-button.dx");
dx> data = Import( "power-button.dx" );
