MarkerShape class abstract

Abstract base class for marker shapes.

Marker shapes are used to render visual markers at connection points, including both ports on nodes and endpoints on connections.

Following the GridStyle pattern, this class provides a common interface for rendering different shapes. Each shape type is implemented as a concrete subclass that defines its own painting logic.

See MarkerShapes for predefined shape constants.

Custom shapes can be created by extending this class and implementing the paint method.
