 // program so that the program does not need deal with shared memory and command
 // buffer management. See gl2_lib.h.  Note that there is a performance gain to
 // be had by changing your code to use command buffers directly by using the
 // GLES2CmdHelper but that entails changing your code to use and deal with
 // shared memory and synchronization issues.
