ES31: TexParameter{if} validation for TEXTURE_2D_MULTISAMPLE on OpenGL 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.
