aaronp64 7f60546f05 Fix CPUParticles2D repeatedly scaling particles with 0 velocity and Align Y ...

CPUParticles2D with Align Y turned on would update particles' transforms based on the velocity when velocity was non-zero, but would not set the transform for zero velocity.  This left the transfrom value from the previous call, which may have already been scaled.  In this case, each call to _particles_process would apply the scale again, causing the particle to repeatedly grow (or shrink for scales < 1.0).

Updated the Align Y logic to always normalize the transform values before scale is applied.
