Excuse my pottymouth.

Why the change?

Currently the regular window sprite looks thicker than the reinforced window sprite because it's missing its top and bottom outlines. This uses the outlines of the full tile regular windows to replace the outlines on the regular window. Now when a regular window is used to replace a broken reinforced window, it fits better beside the other reinforced windows.
