/**
* This demo features the drawing of a centered rectangle and the addition of styled text inside
* the rectangle. The application manages the drawing of shapes and implementation of text rendering
* with specific font and settings.
*
* The following operations are performed:
* - A rectangle is created from the center of the drawing bounds.
* - The rectangle is drawn without a fill and with a white stroke.
* - A custom font is loaded and applied to the drawer.
* - A `TextWriter` is utilized to display the text "hello world" inside the rectangle, adhering to
* specific styling and formatting rules.
*
* Key Components:
* - `application` establishes the visual environment.
* - `Rectangle` provides a way to define the rectangular area.
* - `drawer` enables isolated operations for drawing elements.
* - `writer` facilitates text rendering with alignment and spacing adjustments.
