Optionally ignore/don't invert alpha channel on spherical harmonic directional coloring particle modules
Is your feature request related to a problem? Please describe.
When using a PhotonDust particle color module, e.g. ColorByVelocityDirectionSH1, when the direction of travel goes negative, all channels including alpha get inverted. With an alpha-aware rendering mode on the material, this can cause particles to disappear or render incorrectly. Opaque and cutout modes are unaffected.
I think the behavior is technically correct, but it feels a bit unintuitive and like it may limit the usefulness of these modules somewhat. I don't think its a bug exactly, since I have also used this directional visibility in some particle effects.
Describe the solution you'd like
A boolean toggle on the ColorBy{Velocity,Orientation}SH{1-4} modules that optionally ignores the alpha channel when applying directional inversion of colors.
Describe alternatives you've considered
Not using alpha on my directionally-colored particle effects, I suppose
Additional Context
I made a world that tries to demonstrate this by emitting and bouncing particles around inside a low-poly sphere while flipping between render modes and alpha values. It's a bit flashy and kinda pretty, too.
