Editor is inverting bitmaps on import

In order to begin using the terrain manager I created a number of bitmapped tiles that would fit together seamlessly. However, when I got them into the game they exhibited numerous tears and gross mismatches. So I created a simple test creating a number of flat terrain tiles each of which was numbered so I could see how they were being ordered by the engine.

However when I went to import them into the game to create the terrain I was surprised to discover that the terrain manager was actually inverting the bitmap on import.

The heightmap tile I was importing was this one...


As you can see from the screenshot below the editor is inverting the image. This carries through to the terrain that is created.


This needs to be fixed in order for people who are creating heightmaps using DSGS or hiring artists or mapmakers to create custom maps and especially for folks who plan on using the terrain manager and matching tiles from a larger bitmap together.
