Syntax
public interface ICustomSymbolHitTestRemarks
Carmenta Engine normally implements automatic hit-testing for custom symbols, by hit-testing each call the symbols make to the drawing methods of the drawable.
If a custom symbol needs more control over hit-testing, it may choose to implement this interface, in addition to ICustomSymbol. If it does, Carmenta Engine will call the HitTest method of this interface, instead of doing the automatic hit-testing.
Custom hit-testing is currently not supported in 3D; any area overlapping the screen bounding box for the symbol will be considered a hit.
