Subject: * Apply the other patch from
 http://opensimulator.org/mantis/view.php?id=2315 * This means that LL RAW
 terrains (one source being the upload/download buttons on the estate dialog
 in the viewer) are now imported the 'right' way around rather than being
 flipped on the y axis * Existing RAW terrains before this patch will need to
 be flipped with the "terrain flip y" command from the console after import *
 More details on the mailing lists soon. -This line, and those below, will be
 ignored--
