Subject: HIGHLY EXPERIMENTAL - USE AT YOUR OWN RISK Implement the use of the
 new vmap3-format by Lynx3d (mad props to you for this, and thanks for the
 talks earlier) + reduced Vmap size to less than one third, and improve
 precision + indoor/outdoor check which allows automatic unmounting of players
 + additional area information from WMOAreaTable.dbc, removed existing "hacks"
 + WMO liquid information for swimming and fishing correctly in
 buildings/cities/caves/instances (lava and slime WILL hurt from now on!) -
 buildfiles for windows are not properly done, and will need to be sorted out
 NOTE: Do NOT annoy Lynx3d about this, any issues with this "port" is entirely
 our fault ! THIS REVISION IS CONSIDERED UNSTABLE AND CONTAINS WORK IN
 PROGRESS - USE AT YOUR OWN RISK!
