tyCache Sprite display option

[moonjam]

I'm working on some scenes with a lot of tyCached particles and wondered if it would be possible to get something like the Sprite display mode as a preview option? The current options for viewport optimisation are all fantastic but I find myself missing the fast visual feedback from Sprites when previewing animations for grain like simulations. Alternatively, if that's a pain, something like the mesh override that permits proxy geometry but only in the viewport would be brilliant.

At some point in the future maybe...but right now the tyCache display pipeline is totally different than tyFlow's display pipeline...tyCache was never really meant to have those advanced display modes or features, even though as it's evolved over time it might make sense to have some shared options like that. We'll see...
