[Development] Qt5 subpixel rendering differs from Qt4

Hm, those patched indeed made it look similar, thanx for pointing that out.

But freetype output hasn't changed, rendered glyph image is still paler in
Qt5 than in Qt4, only later rendering of that image makes it similar.

Is there a way to make Qt5 freetype rendering itself similar to Qt4, or at
least replicate what Qt5 does on freetype directly?
