• Fix bug where exiting EditLevel.Texture to Geo Mode would not correctly remember the previous SelectionMode.
• Fix bug where cylinder object sometimes initialize with un-even side lengths.
• Fix bug where on deleting a pb_Object's MeshCollider, ProBuilder would not immediately re-initialize it (prevents common PEBKAC error).

API

• Integrate Doxygen (Still a work in progress - feel free to drop by the forums with any questions).
• Add SharedTrianglesWithFacesExclusive for extracting shared triangle indices exclusive to passed faces.
• VerticesWithIndiceArray is now VerticesWithTriangleArray.
• Remove pb_Object::CreatePrimitive. Use pb_Shape for object creation, or pb_Object::CreateCube(float scale).
• Add OnVertexMovement EventHandler to pb_Object.
• pb_Object::CreateObjectWithPointsfaces is now pb_Object::CreateObjectWithVerticesFaces.

Actions

• Update AutoNodraw to cast from all vertices + center point when determining hidden flag.
• In PivotTool.cs, snap pivot point to grid if no vertices are selected.
• Refactor EntityType.Brush to EntityType.Detail.

Internal

• Add pb_Profiler class
• Add UVee window + ProBuilder specific modifications
• Add internal preference to force update preference when necessary (usually means adding shortcut items).
• Significant performace improvements in handle drawing.
