Remarks

This struct is exclusively for the SDL_HAPTIC_RAMP effect.

The ramp effect starts at start strength and ends at end strength. It augments in linear fashion. If you use attack and fade with a ramp the effects get added to the ramp effect making the effect become quadratic instead of linear.
