    Small bugfix for makeglyphfontspecs call in drawregion
    
    Here's a patch that fixes a bug when calling `makedrawglyphfontspecs'
    in `drawregion'. Wasn't offseting the pointer into the input glyphs
    array by `x1'. The bug isn't causing any problems currently, because
    `drawregion' is always called with `x1' and `y1' values of 0, but if
    this ever changes in the future, the bug would certainly cause some
    problems.
