add more timers in a few spots
by default, display percent timers but don't display elapsed for non-verbose stuff (bmodels); this is so it still shows that it's "working" instead of just showing blank for large maps, give user an idea on progress for certain stuff
merge all "side not found"s into a single line
time `FillOutside`
time `ProcessMapBrushes`
time `Brush_LoadEntity`
fix logging::percent getting stomped in multi-threaded operations
add new stats facility to make creating lists of single-use stats easier to manage
fix SplitBrush storing a bunch of extra stats for ChopBrushes
use some explicit types (bspbrush_t::ptr for pointer, bspbrush_t::container for container of pointers, and bspbrush_t::make_ptr to create one) so that we can swap it out with different pointers easier later
swap out bspbrush_t::ptr from unique_ptr to shared_ptr; it's not important yet, but it does not increase compilation time and will allow us to pass things to functions like SplitBrush without destroying the original as long as we still have a reference to it somewhere (important for ChopBrushes)
add get_positive_plane to mapface_t
instead of creating a whole copy of the bspbrush_t list, BrushBSP now just creates copies of the shared_ptrs which are then filtered down the tree; the originals are never modified by SplitBrushList and friends, only split into new brushes, so this is safe from what I can tell
portals now directly reference the mapface_ts
original_brushes now directly reference the mapbrush_ts
early exit in `BrushBSP` if brush list is empty (moved to top)
"node_t::original_brushes" is now only used during construction and cleared on Prune; original_mapbrushes is used to track the map brushes on nodes post-construction
calculate and cache contents on mapbrush_t
add extra sanity checking to polylib
adjust some warnings to be clearer and not indicate that the world will break
add sanity check to update_bounds, and don't add empty windings to the bounds
fix bug with c_brushesremoved brushes
move & CreateBrushWindings use where required
store the source face we made a bspbrush_t side from
fix test issue
calculate brush bounds (and winding) and add bevels after all of the rest of the map has loaded, so that it has proper world extents
calculate world extents right after the map is loaded
