\brief
    Basic RenderedStringParser class that offers support for the following tags:
    - 'colour' value is a CEGUI colour property value.
    - 'font' value is the name of a font.
    - 'image' value is a CEGUI image property value.
    - 'window' value is the name of a window.
    - 'vert-alignment' value is either top, bottom, centre or stretch.
    - 'padding' value is a CEGUI Rect property value.
    - 'top-padding' value is a float.
    - 'bottom-padding' value is a float.
    - 'left-padding' value is a float.
    - 'right-padding' value is a float.
    - 'image-size' value is a CEGUI size property value.
    - 'image-width' value is a float.
    - 'image-height' value is a float.
    - 'aspect-lock' value is a boolean (NB: this currently has no effect).
