Description
Hi guys,
Just a wild thought: would it make sense to introduce a uniform like "particleStretch" to be able to tweak default particles (which are union quads now) to a different shape (i.e. rectangle)?
Basically, converting billboard rendering into stretched billboard rendering without scaling particle system's entity (to avoid side effects of modifying world transform chain). The change seems trivial and I am happy to submit a pull request if that's fine with your design.

Research direction
Start by locating the particle-system billboard rendering path and reviewing how default quad particles are shaped. Determine whether a particleStretch uniform fits the engine design; done means an agreed implementation that supports rectangular particles without scaling the particle-system entity.
