  Add a Buffer::getIndexRange function.
  
  Instead of exposing the index range cache, add a more generic method that
  allows the buffers to handle their own caching of index ranges.
  BufferImpl::getData can be hard to implement for BufferGL because there
  isn't a way to tell the buffer to unmap and glGetBufferSubData can be very
  expensive, requiring an extra copy of the data.
