//! \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]);
//!   }
//!

//! 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.
