This directory contains code related to on-screen editing knots.

Note that there are classes with similar functionality based on the ControlPoint class in src/ui/tool.

Classes here:

  * SPKnot              A class that describes a knot (size, type, position, state, etc.) with some signals.

  * KnotHolderEntity    A class that has an SPKnot with some signals connections.

      Derived classes:

         LPEKnotHolderEntity
         PatternKnotHolderEntity
         HatchKnotHolderEntity
         FilterKnotHolderEntity

         And many classes derived from above!

  * KnotHolder         A class that has one or more overlapping knots via KnotHolderEntity's.
