[BUG-234589] PRIM_ALIGN_TO_VEL Prim parameter to automatically align prim with it's velocity along a given axis.

[sl-service-account]

How would you like the feature to work?

A prim parameter that makes the sim (or the client if thats all we can get) keep a prim aligned with its velocity.

I would hope to have something like

llRezObjectWithParams( "projectile", [
    REZ_POS, position,
    REZ_ROT, rotation,
    REZ_VEL, vel,
    REZ_FLAGS, REZ_FLAG_TEMP | REZ_FLAG_PHYSICAL | REZ_FLAG_DIE_ON_COLLIDE | REZ_FLAG_DIE_ON_NOENTRY | REZ_FLAG_BLOCK_GRAB_OBJECT
    REZ_ALIGN_TO_VEL, llEuler2Rot(<1,0,0>)
] );

would keep the prim aligned pointing forwards for the furation of its flight.

It'd be great to also have this for llSetLinkPrimitiveParams as a general prim parameter

Why is this feature important to you? How would it benefit the community?

This would work great with the new RezWithParams feature. Allowing projectiles to arc nicely without requiring a script to be inside of them.
