This file is supposed to be auto-generated. Not a problem if you hand edited it,
I can change the script in subsequent CL to generate this output.

[brettw, 2011/06/20 19:31:03]

I searched for a while and couldn't find the original anywhere. Where is it? Can
the generated output list how it was generated?

[alokp, 2011/06/20 19:50:46]

It is generated using gpu/command_buffer/build_gles2_cmd_buffer.py. Sorry the
script has become messy with all the new functionality for ppapi. It is on my
TODO list to separate out the ppapi stuff.
