Contains an array (fontArray) with instances of StrikeFont or TTCFont.
A textStyle comprises the formatting information for composing and displaying a unit (usually a paragraph) of text. Typically one makes a copy of a master textStyle (such as TextStyle default), and then that copy may get altered in the process of editing. Bad things can happen if you do not copy first.
Access to the TextStyle instances is through the TextConstants global.
Note: A TextStyle object does not include Color information. This is a separate property given either directly to a StringMorph or used in an attribute for a Text.
