 # 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 '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.
