Convert Texture to DDS

Just tried this out.  It works but doubles up on the texture uri's in the gltf file?  Is this intended?

	"images": [
		{
			"uri": "PineLeaves_DIFF.png"
		},
		{
			"uri": "PineLeaves_DIFF.dds"
		},
		{
			"uri": "PineLeaves_NORM.png"
		},
		{
			"uri": "PineLeaves_NORM.dds"
		},
		{
			"uri": "PineTrunk_DIFF.png"
		},
		{
			"uri": "PineTrunk_DIFF.dds"
		},
		{
			"uri": "PineTrunk_NORM.png"
		},
		{
			"uri": "PineTrunk_NORM.dds"
		}
	]

I also can't load the converted images into GIMP.  I know it's a plugin issue, but I've not heard of this format.  Just checking it's all good?

Also, none of the generated textures want to load in the editors texture viewer.  They all open externally into GIMP.  Only the normals maps load in GIMP, the diffuse maps show the above error.

Regarding the error in Gimp, for some reason most paint programs don't support modern (last 15 years) DXT compression (BC5, BC6, BC7). Visual Studio itself does have good support for DDS files.

The file "PineLarge_001.gltf" is invalid. There are texture sources listed that exceed the size of the images array.

I hacked it a bit to produce a valid file:

BTW, the asset editor will not load Lods when a model is loaded, since each LOD is contained in a separate file.

The image "PineLeaves_DIFF.png" does not look like it has an alpha channel, or has a completely solid alpha channel.

This seems to be working okay in current build.
