Issue description
Changing the speed_scale of a GPUParticles2D doesn't affect the timing of the finished signal. So, if the speed_scale is set to 0.5, the signal will be emitted in the middle of the effect.
I don't know if this is intentional behavior, and I imagine it's complicated to track the speed_scale in real time. I'm wondering if the initial speed_scale could be used when calculating the duration?
