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! --HG-- branch : trunk
