Remarks

Measure cursor position within a run of text.

The run of text includes the characters from start to end in the text. In addition, the range contextStart to contextEnd is used as context for the purpose of complex text shaping, such as Arabic text potentially shaped differently based on the text next to it.

All text outside the range contextStart..contextEnd is ignored. The text between start and end will be laid out to be measured.

The returned width measurement is the advance from start to offset. It is generally a positive value, no matter the direction of the run. If offset == end, the return value is simply the width of the whole run from start to end.

Ligatures are formed for characters in the range start..end (but not for start..contextStart or end..contextEnd). If offset points to a character in the middle of such a formed ligature, but at a grapheme cluster boundary, the return value will also reflect an advance in the middle of the ligature. See #getOffsetForAdvance for more discussion of grapheme cluster boundaries.

The direction of the run is explicitly specified by isRtl. Thus, this method is suitable only for runs of a single direction.

All indices are relative to the start of text. Further, 0 <= contextStart <= start <= offset <= end <= contextEnd <= text.length must hold on entry.
