bezier splines in envelopes

[TonKazanKezan]

When changing volumes, pannings, effectparameters etc. in envelopes all the ajustments are always straight because of the envelope-'lines' between points. And after using controllers to have some more curved envelope there are a lot of (to much) and difficult adjustable points generated on the envelope. It would be very nice to have the posibility to draw some bezier splines or drawing other types of curves (like the path-tool in photoshop with handles and all) so that the transitions are more 'round'.
