This patch attempts to clean up and document the GPU buffers
code. There are a few bug fixes as well.
Patch reviewed here: http://codereview.appspot.com/4631052/
Summary:
* Bugfix: make GPU_buffer_copy_normal convert from shorts to floats
correctly, also fixed the use of cached face normal CustomData.
* Bugfix: changed the `mat_nr' field of GPUBufferMaterial from char to
short.
* Changed color buffer setup to not alloc a temporary copy of color
data, just passes the MCol data in directly.
* Changed the GPU buffer pool code to make clearer what operates
specifically on the global pool.
* Lots of refactoring for GPU_drawobject_new; should operate mostly
the same (except got rid of one unecessary allocation), just split
into more functions and without macros now.
* Converted some #defines into enumerations.
* Made some stuff private, pulled out of header file.
* Deleted unused function GPU_buffer_pool_free_unused().
* Removed GPU_interleaved_setup and related #defines. (I think this
was used for editmode VBOs, but those were disabled.)
* Added lots of comments.
* Added a few comments in the code signed `--nicholas' to note places
where I am unsure about design or usage, would be good to address
these better.
* Code formatting changed to be more consistent with the rest of
Blender.
* Renamed some fields and variables to be more consistent with
Blender's naming conventions.
* Renamed some fields and variables to use more descriptive names,
e.g. renamed `redir' to `mat_orig_to_new'.
* Removed print outs with DEBUG_VBO -- don't feel too strongly about
this one, just not used elsewhere in Blender, could be easily added
back if others disagree though.
* Moved the PBVH drawing code down to the bottom of the file, before
was sitting in the middle of the other VBO code
