This is not going to do the right thing if the buffer is redefined.

I recommend removing the |transfer_buffer_memory_used_bytes_| state and track
the size of each buffer in the "Buffer" struct.
GetTransferBufferMemoryUsedBytes() can just iterate over all buffers..

Done. After this change the number returned by
GetTransferBufferMemoryUsedBytes() went down to 2MB from 40MB.

   buffers.get(bound_buffer_)->pixels.reset(new uint8[size]);
   if (data != NULL)
     memcpy(buffers.get(bound_buffer_)->pixels.get(), data, size);
