Small Editor mouseover bug

[metal-dad]

In both Canyon and Stadium editor, the mouse-overs on some brushes are incorrect.
Included a few screenshots. The brushes in the red squares are mouse-overs. But I guess that was obvious...
Big pix, I know, but otherwise it wouldn't really be visible...




There are some more brushes with this mouse-over problem, but I think these four will do.

It's not a major bug, but it's a bug, though...
