    tdf#113428: Fix glyph positions in PDF export
    
    Not sure what is going on, but PDF export is the only place we call
    GetNextGlyphs() with nLen > 1 and it seems I broke something here in
    b894104a0b02a9b074c76feb925389d7bee6a493. Instead of trying to figure out
    what the old code was trying to do, lets just calculate glyph positions
    for the extra glyphs as GetNextGlyphs() does for the first one, making
    PDF export closer to how the rendering on screen works.
