Effort/Migrate DrawingLayer

Type: Effort
State: in progress

Rework the DrawingLayer, adhering to ModelViewController design pattern. Decouple DrawingLayer model, view, and geometry information (both data structures and algorithms).

Motivation

Make the DrawingLayer extendible and actually maintainable. Provide means for adding new DrawingLayer shapes easily.

Work already done

• CWS aw024: overlay functionality, migration of geometric tooling to basegfx
• CWS aw033: drawing layer primitives, MVC pattern

Problems

• Maintaining visual equivalence of the rendered output (compared to the old implementation)
