Make the findMetricsForCharacter SVGTextQuery-helper return an iterator
Convert the helper to return an iterator into the metrics vector. Then
use that new property in the calculateGlyphRange helper to avoid O(n^2)
runtime.
Also remove modifyStartEndPositionsRespectingLigatures, because all
users of it (indirectly through
mapStartEndPositionsIntoFragmentCoordinates) now uses the pre-computed
text metrics - which should account for the same thing automatically.
Also fix up the TODO in endPositionOfCharacterCallback by doing what it
says.
