 # A function info object specifies the type and other special data for the
 # command that will be generated. A base function info object is generated by
 # parsing the "raster_cmd_buffer_functions.txt", one for each function in the
 # file. These function info objects can be augmented and their values can be
 # overridden by adding an object to the table below.
 #
 # Must match function names specified in "raster_cmd_buffer_functions.txt".
 #
 # 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.
 # cmd_args:     The arguments to use for the command. This overrides generating
 #               them based on the GL function arguments.
 # data_transfer_methods: Array of methods that are used for transfering the
 #               pointer data.  Possible values: 'immediate', 'shm', 'bucket'.
 #               The default is 'immediate' if the command has one pointer
 #               argument, otherwise 'shm'. One command is generated for each
 #               transfer method. Affects only commands which are not of type
 #               'GETn' or 'GLcharN'.
 #               Note: the command arguments that affect this are the final args,
 #               taking cmd_args override into consideration.
 # impl_func:    Whether or not to generate the GLES2Implementation part of this
 #               command.
 # internal:     If true, this is an internal command only, not exposed to the
 #               client.
 # count:        The number of units per element. For PUTn or PUT types.
 # use_count_func: If True the actual data count needs to be computed; the count
 #               argument specifies the maximum count.
 # unit_test:    If False no service side unit test will be generated.
 # client_test:  If False no client side unit test will be generated.
 # expectation:  If False the unit test will have no expected calls.
 # valid_args:   A dictionary of argument indices to args to use in unit tests
 #               when they can not be automatically determined.
 # invalid_test: False if no invalid test needed.
 # not_shared:   For GENn types, True if objects can't be shared between contexts
