In trunk (r16734) the default CreateCopy() implementation has been altered to try and preserve the NBITS and PIXELTYPE source image structure metadata if it seems to make sense.
In trunk (r16735) the ERS driver has been altered to support reporting PIXELTYPE=SIGNEDBYTE and to honour the PIXELTYPE=SIGNEDBYTE creation option.
In trunk (r16733) a modest test of the above capability has been added to the ers.py script.
The r16735 and r16734 changes have been applied in 1.6 branch (r16736).
