ThemableElement is a helper class for creating new XML elements. This should be preferred over formatting and must be used whenever Fill, Stroke, BackgroundColor or Color contains a color from a theme. i.e. N[1-7] | B[1-6] | AA[245] | AB[45]

func NewThemableElement

func NewThemableElement(tag string) *ThemableElement
