Comment 3 for bug 289676

I forgot to add in the dev build there is also the Lattice Deformation under Path effects, in this effect you get 16 points overlayed over the object and you can move each to deform the object, object deforms more in the part closer to the point.

In Envelope effect you get a square frame around the object, it's divided into 4 paths: top, bottom, left and right, and you edit the paths in the frame to deform the object.

But to get a realistic perspective you have to use Perspective effect, it's hard to fake it using other tools.
