Auto-alignement helper

[NicolasUmiastowski]

Could be intersting to have auto-alignment of shapes helper (as in powerpoint for instance) :
lines appears that show you how to align vertically or horizontally, and they are "magnetic"

[jncraton]

That's a good idea. Everything is already aligned to an invisible 64px grid, so items that are close to one another are easy enough to line up, but this could be helpful for elements that are far from one another.
