Bug#731486: gimp-dds: Unable to save multiple layers as mipmaps

[Tony Houghton]

Package: gimp-dds
Version: 2.2.1-1
Severity: important

I'm trying to create a DDS texture that changes appearance with viewing
distance, but gimp won't let me save multiple layers as mipmaps. In the
"Save as DDS dialog" the "Save: Selected layer" field is greyed out so I
can only save one layer, and the options for Mipmaps: are "No mipmaps"
or "Generate mipmaps"; "Use existing mipmaps" is greyed out. I created
the extra layers by first saving the image as a DDS with "Generate
mipmaps", so the configuration of the layers should be compatible, but
even if I don't make any edits at all, I can't export these layers as
mipmaps. The overall image size is 512x256, the top layer is called
"main surface", and below it are layers "mipmap 1" through "mipmap 9",
each with a width and height half that of the layer above.
