Loaded Worlds are Erratic in Collision Mode

[Cons-Cat]

Description:
There are several issues with collision that has been loaded into the editor from a saved file.

Firstly, terrain viewed in collision mode does not display the correct graphics. Terrain near the top edge of the world boundaries is erratic, and terrain further southward is entirely invisible in collision mode.

Terrain viewed in collision mode cannot be properly selected. The mouse co-ordinates are vertically mis-aligned from the graphics. This is not the case in tiling mode, however.

Toggling the Z-clamp button in the top right corner of the editor resolves this problem.

Additionally, the mini-map does not erase terrain that is lost when a file is opened.
