Improve OTBM load/save and map view performance
This change improves Remere's Map Editor performance in OTBM load/save paths,
object allocation, binary serialization, tile lookup, and idle map rendering.
Measured impact:
Object pool allocation:
- Slab refill events reduced from 17,830 to 2,230, about 87.5% fewer refills.
- 48-byte class refills reduced from 4,276 to 535, about 87.5% fewer refills.
- 64-byte class refills reduced from 5 to 1, about 80.0% fewer refills.
- 128-byte class refills reduced from 8,776 to 1,097, about 87.5% fewer refills.
- 1024-byte class refills reduced from 4,773 to 597, about 87.5% fewer refills.
- rme::allocatePooledObject sampled CPU share reduced from 20.01% to 14.62%,
about 26.9% lower sampled share.
- Total pooled allocation calls stayed at 42,559,971 for the measured workload.
- Heap fallback allocations stayed at 0, confirming the hot load path remains pooled.
Latest mixed load/save profile:
- GUI::LoadMap remained the dominant sampled cost at 67.02%.
- IOMapOTBM::loadMap accounted for 60.23% total sampled CPU, with 56.34% in
the inner load body.
- GUI::SaveMap and Editor::saveMap accounted for 28.16%.
- IOMapOTBM::saveMap accounted for 27.63%.
- BaseMap::forEachTileLocation during save accounted for 23.01%.
- Tile::Tile accounted for 11.53%.
- Tile::addLoadedItem accounted for 8.15%.
- Item::Create accounted for 6.99%.
- QTreeNode::createFloor accounted for 6.71%.
- BinaryNode::advance and BinaryNode::load accounted for 5.37% and 3.81%.
Map view idle and preview rendering:
- Static map-view sampled CPU dropped from 139,767 sampled units to 126 sampled
units after overlay-only refresh reuse.
- MapCanvas::OnPaint dropped from 46,229 sampled units and 32.20% to 19 sampled
units and 15.08%.
- GLRenderer::flushCommands dropped from 24,321 sampled units and 16.94% to
4 sampled units and 3.17%.
- Performance stats refresh changed from a 16 ms scene-dirty timer to a 500 ms
overlay-only timer.
- Show Preview changed from a 16 ms scene-dirty timer to a 250 ms scene-dirty
timer.
- Position indicator keeps the 16 ms scene-dirty timer because it is expected
to animate smoothly while active.
Main changes:
- Added cached floor and tile lookup while loading OTBM map data and spawn files.
- Added direct TileLocation assignment for parser paths that already resolved
the destination location.
- Added BaseMap::forEachTileLocation for direct save traversal of existing tile
locations.
- Added a small-object slab allocator for hot Item, Tile, and Floor allocations.
- Added pool owner-thread binding and diagnostics for allocation validation.
- Increased slab sizing to reduce refill pressure in large-map loads.
- Improved binary node writing by batching raw bytes and avoiding redundant cache
renewal checks.
- Avoided rewriting XML sidecar files when serialized content only differs by
line endings.
- Fixed invalid ground serialization so placeholder ground id 0 no longer drops
the rest of the tile contents during save.
- Split map canvas refresh into scene-dirty and overlay-only paths.
- Adjusted animation timer behavior for position indicator, Show Preview, and
performance stats.
- Scaled tooltip rendering with map zoom, clamped to 55% minimum.
- Kept review and Sonar cleanups away from hot path regressions with targeted
NOSONAR annotations or FORCEINLINE where needed.
- Added AGENTS.md guidance for future Git, build, and PCH discipline.
Notes:
- The Visual Studio captures are sampling profiles, so percentages represent CPU
sample share, not direct wall-clock speedup.
- The latest profile is a mixed interaction profile, not a strict load-only or
save-only benchmark.
- The allocator counters are the strongest before/after measurement in this
change.
- No OTBM format or map semantics are intended to change.

Created the complete organization of npcs, that way, it is possible to create own files for npcs, no longer depending on being together with the monsters
this pull request was made to be worked together with the canary project: https://github.com/opentibiabr/canary
The spawns npcs is "yellow" and spawns monsters is "red" (the old)
With this change, the map will automatically create an "npc.xml" the first time it is saved.
It is possible to edit only the xml, it is not necessary to add or modify the npc by opening the editor map
Thus, there is a script for npcs, similar to how it works with old spawns
Removed libxml2 to use pugixml.
Fixed a bug with the progress bar.
Changed some things in most xml files that pugixml did not like.
Updated the Visual Studio project.
Any NULL symbol has been changed to nullptr.
This most probably broke the CMake that was recently added.
And probably some other things.
Clean git repository since the old svn / git mess was pretty much
unrecoverable unfortunetly. I would have liked to keep the history
for posterity, but that proved to be a futile quest.
