preview shape of nodes

[dzmitry-lahoda]

in editor

a [ shape = box3d]

literally shows

a [ shape = <HERE IS BOX> box3d]

(like color is shown)

or shown visual when you type only (selecting shape from list) or when mouse over.

so instead of rendering I can know what will be ahead

it is hard to find good shape from list as some shapes have weird names
