Card Cluster Impostors

The system is fairly trivial in concept. It generates a specified number of cards (quads) along with textures to represent original mesh.

The idea for this system was inspired by Sean Feeley's talk at GDC 2019 "Interactive Wind and Vegetation in 'God of War'", where he briefly explained how impostors work in their engine.
