* dtIntersectSegSeg2D: Calculate over zy-plane instead.
* dtOverlapPolyPoly2D: Calculate over zy-plane instead.
* dtNavMeshQuery::findRandomPoint: z = h.
* dtNavMeshQuery::raycast: Invert hit normals.
* Update all comments to use xyz vector instead (previously xzy (xz-plane z-height)).
This increases the size of the path lines (this had to be increased due to the scale of the maps in this engine, recast was originally not scaled for it).
* Removed Samples button and dialogue.
* Removed SoloMesh.
* Removed TempObstacles.
* Limit 'Verts Per Poly' to 6 (DT_VERTS_PER_POLYGON).
* Moved hulldef constant and handler to TileMesh.
* Set m_tileSize based on hull (small = 32, med_short = 32, medium = 32, large = 64, extra_large = 64).
* Add missing dtQueryFilter field (some flag used in the engine but not sure yet what it does).
* Set tile->polysEnd and tile->offMeshConsEnd to end of polys and offMeshCons array pointer (if ever needed).
* Set camera perspective to 75 (previous 50).
* Improve theme.
* Lowered the climb height for all hulls (this improves NavMesh generation around low obstacles, previously it would create a poly connecting the ground on the side with the surface of the object around where it connects with the ground, causing AI to take this route instead and kind of 'glitch' onto the surface).
Game gets max 10 seconds to shutdown properly when closed directly by the external console window (g_pHostState->m_iNextState = HostStates_t::HS_SHUTDOWN).
* Changing RCON passwords on the server now closes all connections and re-initializes the system.
* Fully mapped out VFTable interface for IConVar* (used for ConVar callbacks, see callback.cpp).
* Move AIN/NavMesh debug draw to ai_utility_shared.cpp.
* Use shift index + range for AIN debug draw.
* Added cvar for determining max distance between camera and tile (anything outside this range doesn't get draw).
* Pointer to g_pMemAllocSingleton
* New wrapper for returning the singleton, and creating one if not yet initialized (game shares the same pointer, and is aware of its creation).
