Remove obsolete tweak in QFontEngineS60::alphaMapForGlyph
On some Symbian versions (apparently <= Symbian^1),
CFont::GetCharacterData() returns 8-bit data with gray values
0x00, 0x10 ... 0xe0, 0xf0 due to a bug. The glyphs are nowhere
perfectly opaque, which is bad for blitting.
This has been however been fixed for Symbian^3.
The funny thing about this tweak was that it was only executed
on Symbian^3 (with the OpenVG/OpenGL paintengines). On Symbian^1
and below (rasterpaintengine), QFontEngineS60::alphaMapForGlyph()
does not get called at all, anymore.
Therefore, the removal of this tweak should not be noticable
anywhere, except that on Symbian^3, quite a few CPU cycles are
now saved.
See the attachments in QTBUG-14419 for details.
