/**
 * Pixel-perfect scaled fonts for use in the MAP element as defined in skin.dmf
 *
 * Four sizes to choose from, use the sizes as mentioned below.
 * Between the variations and a step there should be an option that fits your use case.
 * BYOND uses pt sizing, different than px used in TGUI. Using px will make it look blurry due to poor antialiasing.
 *
 * Default sizes are prefilled in the macro for ease of use and a consistent visual look.
 * To use a step other than the default in the macro, specify it in a span style.
 * For example: MAPTEXT_PIXELLARI("<span style='font-size: 24pt'>Some large maptext here</span>")
