Say you have a 64x64 icon on a 32x32 map using the new, built in big icon functionality

From what i'm reading in the documentation, only the one 32x32 tile is solid, the rest is not. Is there a library out there that will make the rest of the icon solid?
The effect is purely visual. You'll have to use pre-existing collision methods.
It can be done, however. Creating an invisible dense object and updating it's location every time the owner moves.. not a very good idea, but it'll work.
I created my BigBump library for situations like this because I could never bring myself to use multiple objects like BigAtom does. I have not messed with v456 of BYOND, but BigBump should still work (or at least provide ideas).
