Fonts like "Helvetica Neue UltraLight" or "Skia Regular Black
Condensed" can't be selected in Qt because either they don't
report correct numeric values for weight/stretch/etc. or these
values are not mapped from QFont enums in a linear way. Thus
we provide a shortcut to select these fonts with PostScript
name or full name without resorting to family name matching in
QFontDatabase (these fonts are not registered in font database
anyway). After this, we can simply use:
QFont font("Helvetica Neue");
font.setStyleName("UltraLight");
to select these fonts. QCoreTextFontEngineMulti matched like
this can be created directly from the CTFontRef instance
instead of creating from the font name, making this process
faster.
The commit also cleaned up the font loading process in Mac
font database a bit, moving the code for family matching into
a separate function.
Add QFontInfo::styleName() and QRawFont::styleName() to access
the resolved style name for a font.
