    tdf#93838 windows opengl: fix vertical text position in UniscribeLayout
    
    For one, aPos.Y() is meant to be the baseline position of the text.
    Based on the MSDN documentation and
    <https://www-user.tu-chemnitz.de/~ygu/petzold/ch05c.htm>, that means if
    we want to get top position, we have to only extract tmAscent and not
    tmInternalLeading.
    
    For another, ImplWinFontEntry::AddChunkOfGlyphs() adds a border of 2
    pixels both horizontally and vertically, which means that then we need
    to undo that when counting the vertical position, too.
