render_sprite_trail

Renders animated sprites with trails based on their velocity.

render_rope

Renders all particles in the system into one continuous "rope", the smoothness can be adjusted by changing texel_size and subdivision_count. Killing particles will cause the rope to instantly flick to adjust the rope to remain continuous, so random lifetimes and continuous emitters can look poor, depending on the effect.
