# Named type info object represents a named type that is used in OpenGL call
# arguments.  Each named type defines a set of valid OpenGL call arguments.  The
# named types are used in 'gles2_cmd_buffer_functions.txt'.
# type: The actual GL type of the named type.
# valid: The list of values that are valid for both the client and the service.
# valid_es3: The list of values that are valid in OpenGL ES 3, but not ES 2.
# invalid: Examples of invalid values for the type. At least these values
#          should be tested to be invalid.
# deprecated_es3: The list of values that are valid in OpenGL ES 2, but
#                 deprecated in ES 3.
# is_complete: The list of valid values of type are final and will not be
#              modified during runtime.
# validator: If set to False will prevent creation of a ValueValidator. Values
#            are still expected to be checked for validity and will be tested.

# 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 "gles2_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 "gles2_cmd_buffer_functions.txt".
#
# 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.
# 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.
# needs_size:   If True a data_size field is added to the command.
# 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.
# gen_func:     Name of function that generates GL resource for corresponding
#               bind function.
# states:       array of states that get set by this function corresponding to
#               the given arguments
# no_gl:        no GL function is called.
# valid_args:   A dictionary of argument indices to args to use in unit tests
#               when they can not be automatically determined.
# pepper_interface: The pepper interface that is used for this extension
# pepper_name:  The name of the function as exposed to pepper.
# pepper_args:  A string representing the argument list (what would appear in
#               C/C++ between the parentheses for the function declaration)
#               that the Pepper API expects for this function. Use this only if
#               the stable Pepper API differs from the GLES2 argument list.
# invalid_test: False if no invalid test needed.
# shadowed:     True = the value is shadowed so no glGetXXX call will be made.
# first_element_only: For PUT types, True if only the first element of an
#               array is used and we end up calling the single value
#               corresponding function. eg. TexParameteriv -> TexParameteri
# extension:    Function is an extension to GL and should not be exposed to
#               pepper unless pepper_interface is defined.
# extension_flag: Function is an extension and should be enabled only when
#               the corresponding feature info flag is enabled. Implies
#               'extension': True.
# not_shared:   For GENn types, True if objects can't be shared between contexts
# es3:          ES3 API. True if the function requires an ES3 or WebGL2 context.
# es31:         ES31 API. True if the function requires an WebGL2Compute
#               context.
