Detailed Description

Advanced selection filtering system.

Provides various filters to refine selections:

Attribute-based filtering (scalar values, colors, etc.)
Geometric filtering (area, angle, distance)
Spatial filtering (bounding box, distance from point)
Combinatorial filtering (AND, OR, NOT operations)

Based on ParaView's selection filter functionality.
