 /**
  * GrInOrderDrawBuffer is an implementation of GrDrawTarget that queues up draws for eventual
  * playback into a GrGpu. In theory one draw buffer could playback into another. When index or
  * vertex buffers are used as geometry sources it is the callers the draw buffer only holds
  * references to the buffers. It is the callers responsibility to ensure that the data is still
  * valid when the draw buffer is played back into a GrGpu. Similarly, it is the caller's
  * responsibility to ensure that all referenced textures, buffers, and render-targets are associated
  * in the GrGpu object that the buffer is played back into. The buffer requires VB and IB pools to
