PZ Mapping Tools - Build 20260909f - Perfs & Fixes, second round

Tilesets can be found at: https://drive.google.com/file/d/16Xo3UE0pYRSXS5RtUVr1Izb4wUhz67Sd/view?usp=drive_link

All applications

• All three applications use the same loading window, with a completed
  tileset counter and progress bar. Their main windows start centered at
  1920 x 1080, fitted to the available desktop including window borders.
  Saved dock layouts and temporary window-size overrides remain available.

• TileZed, BuildingEd and WorldEd prepare tilesheet images in parallel with
  a processor-aware limit of eight workers. Complete catalogue loading,
  ordered map declarations and shared image deduplication are preserved.
  WorldEd also retains atlas coordinates when copying newly added tiles
  from the image cache.

• Building Tiles ignores exact duplicate material definitions when reading
  and saving catalogues. The bundled catalogue no longer contains repeated
  entries. Definitions with different orientations or offsets remain separate,
  and the first occurrence retains its position and default selection.

TileZed

• TileZed includes a native TileSetZ editor in Tools and tile context menus.
  It opens and saves PNG tilesheets, paints individual tiles with Undo,
  precuts textures into individual 1x or 2x wall tiles, and generates sheets from the original
  wall, floor, curb, roof-wall, roof and extended wall masks. Custom PNG masks
  support magenta selection or their alpha channel. Generation has a preview
  before insertion, trim colors are editable, and appending preserves existing
  IDs. Saves refresh sheets in the configured Tiles catalogue and detect
  external file changes before overwriting. Drawing has its own tab with
  illustrated tools, shapes, opacity, panning and pixel zoom up to 32x.
  Tilesheet and mask previews have a separate tab with full-tile inspection.
  Wall cuts use the source dimensions and fixed wall-face size to determine
  the tile count automatically. Each source piece is projected without
  resampling, with transparent padding for partial edges and consecutive IDs
  in source row order. Both wall directions, a source cut grid, an assembly
  check and PNG plus TMX export are available.
• TileZed's Depth Map Editor adds a selectable color depth palette,
  alpha-masked painting, source and grayscale preview modes, and undoable
  inversion. Pixel estimates distinguish ground surfaces from vertical
  objects using the game's projection. Volumes update their preview while
  moved or resized, support Undo and Redo, and can be fitted to the sprite.
  Shift-drag adjusts elevation. Generate All replaces the depth tile with
  the preview, while Merge Selected adds the selected volume to existing depth.
• TileZed selections limited to the current layer and level paste onto the
  destination layer. Broader selection scopes retain layer names and relative
  levels for copying complete structures, even with only one populated layer.
• TileZed and BuildingEd palette context menus offer a saved Show Tile Numbers
  toggle. Erasing a curb restores its blend suppression when no remaining
  neighboring curb needs it. Undo restores the curb and its blend flags.
• Exterior building tiles without a floor retain map tiles on other layers,
  including vegetation. Matching layers are replaced and building floors
  continue to cover underlying map tiles in rendering and export.
• Raster drawing reuses filtered tile images at supported 25% and 50%
  zooms with a bounded cache. Edited images select fresh cache entries.
• TileZed and BuildingEd avoid rewriting unchanged window and dock settings.
• TileZed and WorldEd show their application name and build identifier before
  a document is opened.
• Depth-map volume generation prepares primitive transforms once per render
  and shares the camera ray between primitives at each pixel.
• TileZed generates and removes RoomDefs on negative as well as positive map
  levels. New RoomDefs belong to the correct level, and layer-name lookups
  recognize signed level prefixes.

PZWorldEd

• WorldEd exports legacy Professions = all SpawnPoints as unemployed,
  preserving other explicitly selected professions and avoiding duplicates.
  Existing rectangular SpawnPoints retain their original position and size.
  The saved project is unchanged by the conversion.
• The LotPack Viewer restores Save Screenshot and F12, with PNG output to
  a chosen destination.
• WorldEd preserves existing rectangular RoomTone objects during Lua export.
  Their original position and dimensions are retained, and EntireBuilding
  may be omitted for room scope, as supported by the game.
• WorldEd keeps room and building groups separate between source cells during
  LOT generation. Connected underground complexes retain their room definitions
  when neighboring cells are converted and exported separately.
• Thumbnails of buildings placed with basements retain their above-ground
  floors. Underground floors are excluded from the displayed variant.
• Camera zoom retains existing object geometry and basement previews. Labels
  follow geometry edits, including points and polylines. Tile-ordering buffers
  are reused between drawing operations.
• Search groups rapid typing on large worlds and runs immediately on Enter.
  It reuses unchanged result rows and retains each world's search when views
  change or a cell is closed. Empty property-definition lists are safe.

BuildingEd

• Materials refresh on the first Iso/Tiles switch, including after changing
  floors. Custom furniture groups appear immediately when selected in Building
  Tiles, including groups loaded after the dialog was created.
• Object tools use distinct keyboard shortcut identifiers. Shortcut edits save
  immediately and save errors are reported. Reopening the shortcut editor
  retains unsaved edits if a previous save failed.
• Rotations and mirrors retain painted tile positions, square attributes,
  selections and the supported basement-access footprint with Undo and Redo.
  Painted sprite IDs stay unchanged. Border tiles that would leave the
  supported area are identified before the operation changes anything.
• Undo restores furniture positions correctly for asymmetric or aliased tile
  variants after rotations and mirrors.
• Changes between editing modes retain selections. Isometric views share
  their camera position and zoom without cumulative center drift.
• Selecting the active floor again avoids redundant updates. Room highlight
  regions are reused until building geometry changes.
