This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.

One important thing to keep in mind when using this feature is that you'll need to flip your textures vertically (both the GIMP and Photoshop DDS tools I've seen have support for this on export). This is a quirk in using a texture format originally made for DirectX/DirectDraw, and flipping the compressed data is a real headache. Another quick fix for this issue is to change the Y value for the Size in the Mapping panel in the Texture properties to -1 (default is 1).

DXT1 .dds textures with 1-bit alpha channel have their alpha channel imported in Blender.
The patch also makes change to contact info for the patch submitter.
I left the sync with upstream nvtt for another commit.
[#15135] imbuf DDS support: sync to nvidia texture tools revision 602 + fix for ATI2 compressed normal maps
It just updates the dds stuff.

Notes From the author:
The attached patch syncs the DDS code in Blender with the latest revision
(324) of the nvidia texture tools. This fixes a few minor issues and adds
support for a more types of DDS textures, in particular uncompressed textures
that don't have the standard 16, 24, or 32 bits per pixel.
Note: I have started using the nvidia texture tools convention for naming
integer types (uint, uint16, uint8, uint64 etc.) because doing so makes it
much easier to merge patches from upstream. Since the code is compiled
separately from the rest of Blender, this likely does not pose a problem.
However, if there turns out to be a good reason for avoiding those nvidia type
names from upstream, I'd be happy to fix it.
Regards,
Amorilia
