### Samplers
Which samplers are used for textures are specified by the preset format.
The sampler remains constant throughout the frame, there is currently no way to select samplers on a frame-by-frame basic.
The sampler remains constant throughout the frame, there is currently no way to select samplers on a frame-by-frame basis.
This is mostly to make it possible to use the spec in GLES2 as GLES2 has no concept of separate samplers and images.
