Add extension method for loading mipmap texture from stream about fna HOT 3 CLOSED

Does DDSFromStreamEXT handle this? AFAIK it's the only format that natively supports mip levels.

Looks like it would. We'd need to change our asset pipeline. Is there a recommended way to generate DDS files?

I'm aware of the NVIDIA Texture Tools, but most image editors have an exporter for DDS - for an automated solution it may be enough to throw together a quick DDS spewer, as the format is a small header followed by byte chunks with lengths prepended:

• https://github.com/FNA-XNA/FNA/blob/master/src/Graphics/Texture2D.cs#L532

(This is also a good place to compress the texture data to DXT5/BC7, if VRAM usage becomes an issue)
