      Very basic test to just see if mip levels are generated correctly.

      vulkan: add support for mipmaps · b2cc7c6a
      Niklas Haas authored 
      This is a very low quality implementation which simply uses iterated
bilinear scaling, destroying information. It would be much better to use
either a polyphasic filter or, better yet, an actual filter kernel, but
this is more complicated to achieve because the low-level nature of the
vk_tex_* implementation prevents me from using high-level public APIs,
so I will defer it to a future commit.

      gpu: add support for pl_tex_params.mipmaps · 6a7fbdf7

      This commit just adds the public facing API. I decided to go with a
"minimalist" approach of just making mipmaps transparently regenerate
without user intervention, any time a texture containing mipmaps is
sampled from. (Of course, the validity of mipmaps will be cached, and
they will only be re-resolved if the texture is written to)
