Detailed Description

Central QGraphicsScene subclass that holds all map-layer graphics items.

Layers populate the scene with QGraphicsItems via OpenSWMMVisLayer::populateScene() / depopulateScene(). The scene uses BSP-tree indexing for efficient hit-testing and spatial queries.

The scene coordinates are in map CRS units:

X increases to the right.
Y increases upward (geographic convention).

The associated QGraphicsView (MapCanvas) applies a vertical flip in its transform so that screen-Y-down maps to geo-Y-up.
