Subject: [PATCH] Mantis#1544. Thank you kindly, Jonc, for a patch that:
 Terrain revert using the PaintBrushes appears to work OK, however when using
 'apply to selection' the RevertArea FloodEffect calculates the revert height
 incorrectly unless the strength passed in from the viewer is 1.0 Attaching a
 patch to correctly reset the selected area to the heights in the revertmap.
