Returns the next cursor position in the run. This avoids placing the cursor between surrogates, between characters that form conjuncts, between base characters and combining marks, or within a reordering cluster.
The context is the shaping context for cursor movement, generally the bounds of the metric span enclosing the cursor in the direction of movement. contextStart, contextEnd and offset are relative to the start of the string.
If cursorOpt is CURSOR_AT and the offset is not a valid cursor position, this returns -1. Otherwise this will never return a value before contextStart or after contextEnd.
