Generic force-feedback effect envelope
@attack_length: duration of the attack (ms)
@attack_level: level at the beginning of the attack
@fade_length: duration of fade (ms)
@fade_level: level at the end of fade
The @attack_level and @fade_level are absolute values; when applying
envelope force-feedback core will convert to positive/negative
value based on polarity of the default level of the effect.
Valid range for the attack and fade levels is 0x0000 - 0x7fff
