Hi,

I have a problem displaying rotated text in Wine where the
rotation under Windows is counterclockwise, but the rotation
in Wine is clockwise.
The patch I came up with rotates the text in the right direction,
but the individual characters are still rotated in the wrong
direction.
The attached WMF file shows the bug.

Any help/criticism would be appreciated.
