The character offset of the glyph, relative to the current [RichTextEffect] custom block. Setting this property won't affect drawing.

|

The current transform of the current glyph. It can be overridden (for example, by driving the position and rotation from a curve). You can also alter the existing value to apply transforms on top of other effects.

|

If [code]true[/code], the character will be drawn. If [code]false[/code], the character will be hidden. Characters around hidden characters will reflow to take the space of hidden characters. If this is not desired, set their [member color] to [code]Color(1, 1, 1, 0)[/code] instead.
