For my compile of UVPov compared against the official windows version, both
images were identical.  Removing the "#version 3.1" did change the image.
The reason is that by default UVPov treats layered textures differently.  It
treats filter like filter and transmit like transmit (the official version
treats both filter and transmit like transmit).  Adding "#version 3.1"
enables backwards compatibility.
