I imagine if there's some way to reasonably fast package the non walkable pixels into boxes (static bodies with rectangle shape) then we could have a function that loads the walkable areas into the world.

Other idea is Moore Neighbor tracing
Potrace may be useful.
Also XAGE has a similar converter to polygons for walkable areas on AGS Export plug-in
