Create mipmapped textures

Next, let's create mipmapped KTX files using filament's mipgen tool. We'll create compressed and non-compressed variants for each texture, since not all platforms support the same compression formats. First copy over the PNG files from the monkey folder, then do:

-

For more information on mipgen's arguments and supported formats, do mipgen --help.
