Description
If a thematic hfa file is exported from gdal, it shows up correctly as thematic in gdalinfo, but ERDAS Imagine (v9.1 was tested) detects this as athematic/continuous.
This appears to be related to the way statistics, in particular histogram/mapping data is reported.
If histogram is dumped as reals instead of ints, and the BinFunction is set to direct instead of linear then Imagine correctly see's a thematic data set.
Two sample files from Imagine are attached, 1x1 images, one is thematic and one is athematic.

Patch applied in trunk (r26024).
The existing tests pass, but it would be nice to add something to confirm proper behavior here.
I'm somewhat hesitant to back port this to 1.10.x unless we can get feedback from some key users that everything still works right. Reopen if you would like to pursue that.
