[npe] Project to Screen node, e.g. for particle direction

We only accept feature requests that are discussed on the BabylonJS forum

Is your feature request related to a problem? Please describe.
Need a way to control the angle of particles so it matches the particle direction. This is very useful for particle systems with streaks or sparks that needs to be oriented along the particles velocity (direction).

The closest I could get is this: Babylon.js Node Particle Editor (but only works from the right viewpoint)

Describe the solution you'd like
I assume angle is in screen (camera) space, while direction is in local space - so would need a node to e.g. project direction to camera space
