When setting parameters by TexParameter{if} for TEXTURE_2D_MULTISAMPLE,
an INVALID_ENUM error is generated if target is TEXTURE_2D_MULTISAMPLE,
and pname is any sampler state from table 20.11. An INVALID_OPERATION
error is generated if target is TEXTURE_2D_MULTISAMPLE, and pname
TEXTURE_BASE_LEVEL is set to a value other than zero.
