Edge of a room is not rendered (Simple Map Builder)

[Zij-IT]

While exploring a map generated by the simple_map_builder I noticed that some edges in rooms are not properly rendered, or may not be a part of the map. I am currently unsure of the exact location of the bug, as it could be one of two things:

• Rendering issue regarding EDGE_BUFFER as it prevents the edge of the room from being rendered.
• Map building issue as the boundaries of a room may not be checked to be valid for the simple builder. This will have to be verified later.

Resolved via commit c50d6d0 after noticing that the issue was not just with Simple Map Builders, but also with Cellullar created maps.
