Observed result:
Particle emitter image does not scale to fit the particle box in layout view. Preview will not show the particle according to layout view either. Particle does not rotate also.
Expected result:
Particle image should fit in the Particle BBox in the layout view. Particle should be scaled according to the particle box when previewing. Particle should be rotated.
Steps to reproduce
Create a particle emitter, draw something or load an image.
Return to layout and try scaling the particle box. Image stays 1:1 size always even if you scale the particle emitter box, and be rotated accordingly.
Preview layout and particle is not scaled according to the box for the particle emitter in layout view.
