I think it would be nicer to have "invalid target = %s",
_mesa_lookup_enum_by_nr(target) in your error message, because otherwise
the user might have to go looking through Mesa to find out which incorrect
target they passed. For example, not everyone knows that 3553 =
GL_TEXTURE_2D. (Although I do, for some sick reason :))
