Originally taken from https://github.com/ASpoonPlaysGames/r2recast, slightly modified to use the new constants added in commit 78a632eec85ca5406adb03617084746b446b0044, and now renders white crosses if reverse links are set.
The dtNavMesh structure members were marked as public, but they should be private. Made them private. Also, dtNavMesh::addTile was reconstructing all links, even when we add tiles with pre-existing links. The link building logic has been moved to a new member function 'dtNavMesh::connectTile'. This should only be called once the navmesh tile has been added succesfully during build. If we load a navmesh now, the existing links will be used from now on. The dtNavMesh::m_tileCount member is now also correctly incremented and decremented in addTile/removetile.
Don't render the geom off-mesh connection, this is already done when the tool is enabled, and we don't want to render it outside the tool since it would overlap with the built off-mesh connection.
Tool states aren't always set, they are typically only set for the active tool if an option changed, but if nothing changed, then nothing will get updated (including the navmesh handle) so dangling pointers will be used. This makes sure everything gets initialized.
This is useful when a project file (.GSET) has been loaded with predetermined navmesh bounds, which allows you to check the new bounds to the old, and also see what you will be resetting too if mistakes were made during the modification thereof.
When loading from .gset, the editor would clip anything outside the stored bounds, but we still need the outer bounds as otherwise editing the existing bounds would be a lot harder.
There was an issue where Recast's common math library was less complete than that of Detour. Some common math operations were also isolated in specific translation units causing copies everywhere. All common math operations have been moved to the Shared library ultimately fixing all the above issues.
User can now define where the navmesh will be build and what would be excluded in the map. Also adjusted some colors of existing bounding boxes to make them more visible. They weren't as visible as they used to be after the UX and rendering improvements.
New ability to adjust it in all directions, recast and detour offsets are separate. By default, the Recast mesh renders 20 units from the input geom and Detour 30 units to avoid z-fighting.
Move common code to Editor_Common and fix solomesh. Solomesh is useful for debugging recast as it allows for generating everything in 1 tile. Also did numerous fixes for the tilecache code, though this is still broken and won't be really used for the r5sdk project, but its nice to have for a potential project outside r5sdk that uses the xyz coordination system, which avoids having to run the navmesh through a conversion pass in runtime.
