Fix DirectWrite engine when loading from data through QRawFont

Browse Source 
The stretch, once it is passed to the font engine, is assumed to
be the horizontal scale needed to match the requested stretch
for the given font. When loading from data in QRawFont, there
is no way to specify this stretch; the scale should always be 1.

The effect of this was that when DirectWrite was backing a font
loaded through QRawFont directly from data, then the glyph images
would be scaled to 0xHEIGHT before they were returned, thus
they would be empty.

This was a regression caused by
ec7fee968f.
