The TextImage datatype allows for generation of an image of text based on settings (color, background, font, size, position, etc..)
It allows the use of server fonts as well as a custom font (TTF file)
It appears on doctypes as a standard textbox, but generates an image file on save (displayed in a preview)
<img src="{$textImage/TextImage/Url}" alt="{$textImage/TextImage/Text}"/>
