Remove unnecessary calls to GetHorizBounds() + boundingBox()
QFontEngineS60::boundingBox_const(): The metrics that
CFont::getCharacterData() returns is equivalent to what
TOpenFontCharMetrics::GetHorizBounds() returns. So, remove
the use of TRect glyphBounds, and
TOpenFontCharMetrics::GetHorizBounds().
Implementation of TOpenFontCharMetrics::GetHorizBounds():
http://developer.symbian.org/oss/API_REF/Public_API/file/837f303aceeb/epoc32/include/openfont.h#l1352
QRasterPaintEngine::drawGlyphsS60(): The metrics that
QFontEngineS60::getCharacterData() returns are equivalent to
what QFontEngineS60::boundingBox() returns. So, remove the
use of glyph_metrics_t metrics, and QFontEngineS60::boundingBox().
These changes increase the Fps in
qt\tests\manual\textrendering\textperformance "Latin" from 16.2 to
16.5 Fps on an XM5800. And they do that by removing code :)
