+# Must match function names specified in "cmd_buffer_functions.txt".
+#
+# cmd_comment: A comment added to the cmd format.

+# 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

+# data_transfer_methods: Array of methods that are used for transfering the

+# The default is 'immediate' if the command has one pointer

+# needs_size: If true a data_size field is added to the command.

+# 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

+# 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
+# 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

+//! \file
+//!
+//! The public interface for 3D graphics is based on a command buffer.
+//!
+//! This was chosen because it provides an easy way to separate the process of
+//! writing commands from the process of reading those commands without
+//! requiring too much overhead to keep the two processes in sync.
+//!
+//! You can use this info to write commands yourself. Most developers will use
+//! the provided OpenGL ES 2.0 implementation that issues these commands for
+//! them.
+//!
+//! Each command starts with a header. The header is 32 bits, where the first 21
+//! bits define the number of 32 bit entries, including the header, the command
+//! represents. The last 11 bits specify the command.
+//!
+//! Commands that send a variable amount of data have 1 to 3 ways to send that
+//! data.
+//!
+//! Many commands can send their data in shared memory. The command will take
+//! an id of the shared memory and an offset into that shared memory of where
+//! the data lives. Commands are executed asynchronously, so the client
+//! program must be careful to leave the data available until the command has
+//! executed.
+//!
+//! Some commands have an 'immediate' version where the data appears directly
+//! after the command in memory.
+//!
+//! A 3rd way of passing data is through Buckets. Buckets are identified by
+//! number. You create a bucket with the command SetBucketSize, you can then
+//! fill the bucket with SetBucketData commands. Once you've sent all your
+//! data you can then issue a command that uses the bucket and takes a bucket
+//! id for which bucket to use.
+//!
+//! Receiving data works similarly. Some commands return their data to shared
+//! memory. Other commands return their data through buckets which can then be
+//! queried with the GetBucketSize and GetBucketData commands. In either case
+//! the data will not be available until the command executes.
+//!
+//! All commands and arguments are validated. If a command fails validation the
+//! service will stop processing commands. It is the responsibility of the
+//! client to never issue an invalid command.
+//!
+//! Examples of invalid commands.
+//! - A command's size does not match the command.
+//! - A command's size would address memory outside the command buffer
+//! - A shared memory id is invalid
+//! - A shared memory offset is out of range for the given shared memory
+//! - The size of the data a command would access in shared memory is out of
+//! range for the given shared memory buffer.
+//! - A result (in the transfer buffer) is not initialized to the
+//! failure case. For example, any command that returns a SizedResult
+//! will take a shared memory id and offset to where to store the result.
+//! That size field of the result must be set to 0 before issuing the
+//! the command. That way, if the command buffer service fails the
+//! client will see a 0 size.
+//!
+//! The docs are a little terse. For any command that corresponds to an OpenGL
+//! ES 2.0 function the arguments should be clear by looking at the OpenGL ES
+//! 2.0 documentation with minor caveats.
+//!
+//! - Client side arrays are not supported at the command buffer level
+//! so DrawArrays and VertexAttribPointer only take offsets into buffers.
+//! - The commands GenBuffers, GetTextures, CreateProgram, CreateShader, etc
+//! take client side ids and register them with the service. It's up to the
+//! client to make up the ids.
+//! - For shared resources, it's still up to the client to make up ids.
+//! but to help keep them in sync with other threads the commands
+//! GenSharedIds, RegisterSharedIds and DeleteSharedIds can be used.
+//!
+
+//! The command header.
+struct CommandHeader {
+ Uint32 size:21;
+ Uint32 command:11;
+};
+
+
+//! Used for some glGetXXX commands that return a result through a pointer. We
+//! need to know if the command succeeded or not and the size of the result. If
+//! the command failed its result size will 0. You must set the size to 0
+//! before issuing the command.
+//!
+//! To retrieve the data you might do something like this pseudo code:
+//!
+//! GetAttachedShaders::Result* result = address-of-shared-memory
+//! int num_results = result->size / sizeof(GLuint); // the type returned
+//! GLuint* results = &result->data;
+//! for (int ii = 0; ii < num_results; ++ii) {
+//! printf("%d\n", results[ii]);
+//! }
+//!
+template <typename T>
+struct SizedResult {
+ uint32 size; // in bytes.
+ T data; // this is just here to get an offset.
+};
+
+
+//! A Noop command.
+struct Noop {
+ static const CommandId kCmdId = 0;

+//! The SetToken command puts a token in the command stream that you can
+//! use to check if that token has been passed in the command stream.
+struct SetToken {
+ static const CommandId kCmdId = 1;
+
+ CommandHeader header;

+};
+
+//! The Jump command jumps to another place in the command buffer.
+struct Jump {
+ static const CommandId kCmdId = 3;
+
+ CommandHeader header;
+ uint32 offset;
+};
+
+//! The JumpRelative command jumps to another place in the command buffer
+//! relative to the end of this command. In other words. JumpRelative with an
+//! offset of zero is effectively a no-op.
+struct JumpRelative {
+ static const CommandId kCmdId = 4;
+

+//! Return command.

+//! Sets the size of a bucket for collecting data on the service side.
+//! This is a utility for gathering data on the service side so it can be used
+//! all at once when some service side API is called. It removes the need to
+//! add special commands just to support a particular API. For example, any API
+//! command that needs a string needs a way to send that string to the API over
+//! the command buffers. While you can require that the command buffer or
+//! transfer buffer be large enough to hold the largest string you can send,
+//! using this command removes that restriction by letting you send smaller
+//! pieces over and build up the data on the service side.
+//!
+//! You can clear a bucket on the service side and thereby free memory by
+//! sending a size of 0.
