 # cmd_comment:  A comment added to the cmd format.
 # type:         defines which handler will be used to generate code.
 # decoder_func: defines which function to call in the decoder to execute the
 #               corresponding GL command. If not specified the GL command will
 #               be called directly.
 # gl_test_func: GL function that is expected to be called when testing.
 # cmd_args:     The arguments to use for the command. This overrides generating
 #               them based on the GL function arguments.
 #               a NonImmediate type is a type that stays a pointer even in
