Optimize QFontEngineS60::recalcAdvances()
(Addition to ab057be7228d20d909246183505b72e821cc440f)
Instead of using a glyph_metrics_t (which gets filled with
data from a TOpenFontCharMetrics), we use a
TOpenFontCharMetrics, directly.
Also, the advances_y gets set to 0. Like on the other
platforms.
These change increases the Fps in
qt\tests\manual\textrendering\textperformance "Latin" from 16.5 to
16.6 Fps on an XM5800. I am sure that I can construct a benchmark
where the speed gain is bigger.
