ConeEmitterShape class Particles

Emits particles from a disc of radius in the local XZ plane, each headed within a cone of half-angle angle about +Y.

The disc is sampled area-uniform and the directions are sampled uniform over the cone's solid angle, so neither the centre nor the axis is over-weighted.
