Position represents a position on the screen that can either be absolute or relative, depending on the context.

ShaderCollection holds the set of shaders to be used for rendering.

Size represents the dimensions of something on the screen.

Spacing represents a spacing around or inside a given screen entity (e.g.

Typography configures how text is to be drawn.
