[Feature Request] Transparency + Antialiasing

[microfx]

I'd love to see some transparency (to add some background gradients to the color palette from background) or even add some nice gradients options ... so I guess these are two feature requests in one :D one or both things would be awesome to let it look way cooler!

Also I am noticing a lot of aliasing in the curves – would also be nice to have one step more of antialiasing.

Cheers!
