No they're not. Textures need to be completely independent: coordinate
in -> values out. Although textures may look like simple images, they
have more functionality than this, such as filtering, mipmaps, etc.
which can change depending on the input derivatives. You can generate
images from textures (by sampling the texture at every pixel in the
image buffer), but you can't go the other way around, as part of a
shading pipeline at least.
