# This table specifies types and other special data for the commands that
# will be generated.
#
# Must match function names specified in "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.
# a NonImmediate type is a type that stays a pointer even in
# and immediate version of acommand.
# gen_cmd: Whether or not this function geneates a command. Default = True.
# immediate: Whether or not to generate an immediate command for the GL
# function. The default is if there is exactly 1 pointer argument
# in the GL function an immediate command is generated.
# bucket: True to generate a bucket version of the command.
# impl_func: Whether or not to generate the GLES2Implementation part of this
# command.
# impl_decl: Whether or not to generate the GLES2Implementation declaration
# for this command.
# needs_size: If true a data_size field is added to the command.
# data_type: The type of data the command uses. For PUTn or PUT types.
# count: The number of units per element. For PUTn or PUT types.
# 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
# state_flag: name of flag that is set to true when function is called.
# 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
# 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
