max_lod
Maximum level of detail, used to clamp LOD after bias.
border_color
RGBA color used for texel coordinates that are outside the [0,width-1],
[0, height-1] or [0, depth-1] ranges.
Color union used for texel coordinates that are outside the [0,width-1],
[0, height-1] or [0, depth-1] ranges. Interpreted according to sampler
view format.
max_anisotropy
Maximum anistropy ratio to use when sampling from textures. For example,
if max_anistropy=4, a region of up to 1 by 4 texels will be sampled.
