Added, "Check polyobjects" error check: added a check for matching Polyobject and Mirror Polyobject numbers of Polyobj_StartLine action. Changed, Visual mode: anisotropic filtering is now always applied (previously it was applied only when bilinear filtering was enabled). Fixed, Visual mode: in some cases light values were incorrectly transferred between 3d floors and regular floors/ceilings. Fixed, ACS parser: includes for each library must be stored separately (fixes inability to compile a script with an included library, which in turn includes files already included by the script).
