Title: Improve label readability

A while back I tweaked BillboardCollectionVS.glsl to align to pixel in one direction. This improved text legibility somewhat, but in many cases text still gets pretty ugly. It also caused images to look worse in some cases. This change adds a `BillboardCollection.clampToPixel` boolean property which aligns all vertices to a pixel in screen space. I then updated the LabelCollection to turn it on by default (it's off by default for Billboards).

The end result is more readable text and smoother non-text billboard animation.

Look out @pjcozzi I'm learning just enough about graphics to be dangerous ;)
