    Class AcApContext

    Application context that binds a CAD document with its associated view.

    This class establishes the connection between a CAD document (containing the drawing database) and its visual representation (the view). It handles event forwarding between the document and view to keep them synchronized.

    The context manages:

    • Entity lifecycle events (add, modify, remove)
    • Layer visibility changes
    • System variable changes (like point display mode)
    • Entity selection and highlighting
    const document = new AcApDocument();
    const view = new AcTrView2d();
    const context = new AcApContext(view, document);

    // The context will automatically sync changes between document and view
    // For example, when entities are added to the document, they appear in the view
