GPU: Allow the user to set an anisotropic filtering setting below the implementation-defined value of GL_MAX_TEXTURE_MAX_ANISOTROPY_EXT

Allow the user to set an anisotropic filtering setting below the implementation-defined value of `GL_MAX_TEXTURE_MAX_ANISOTROPY_EXT`.

This bug-fix is also needed for 2.93 LTS.
