/* TODO: This causes the texture to be loaded always in Mapper.cpp . The

* shape that has a new buffer coming in will overdraw the old buffer of the
* shape on top. This implementation seems to be fast enough that
* _videoNewBufferCounter is often 1 or 0. If bitsChanged is often switching
* between true and false (as in the case described above), than the shape
* textures will appear to be flickering/alternating. Maybe a better solution is
