UltimateZoneBuilder/Source/Plugins/BuilderModes/ClassicModes/DrawGeometryMode.cs
MaxED 4e52d9bb9c Sectors mode: optimized rectangular selection logic.
Sectors mode: optimized sector highlight rendering logic.
Sectors mode: optimized sector effect/tag labels update logic.
Geometry tools: optimized several core functions.
Hints for current editing mode can now be displayed when nothing is highlighted (currently the hints are shown only in Draw Geometry mode).  
GZDB is now build with LARGEADDRESSAWARE flag, which increases amount of RAM GZDB can use from 1.4 to 2.8 GB.
