true if the glyph at
glyph exceeds the bounds of the line fragment where it’s laid out,
Exceeding bounds can happen when text is set at a fixed line height. For example, if the user specifies a fixed line height of 12 points and sets the font size to 24 points, the glyphs will exceed their layout rectangles.
This method causes glyph generation and layout for the line fragment containing the specified glyph, or if noncontiguous layout is not enabled, up to and including that line fragment.
Glyphs that draw outside their line fragment rectangles aren’t considered when calculating enclosing rectangles with the
rect methods. They are, however, considered by
