Working on improving performance

With the addition of the high-res protocols, the target resolutions quickly went from hundreds or thousands of pixels to millions. So I now desperately need to improve performance. So far it’s looking promising:

• A whole model covering the camera 6 moving at 4k went from about 8 fps to 20-30 fps. Not ideal yet, but I think we’re on the right track.

• Super dense meshes (more than 2 million polygons) improved 2-3x

• Meshes with transparent parts improved about 2x

While these wins may seem really big (they kinda are), the jump in resolutions still means they are barely usable interactively. I do want to add gpu acceleration later (with the cpu path as a fallback), but until then I want to make it as fast as I possibly can.
