Subject: Fixed layout of labels so that they are layed out in the proper coordinate system:
X-Git-Tag: glabels-2_3_0~870
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=80c7efe71c394abaab547eee7172ec4c24f2067f;p=glabels

Fixed layout of labels so that they are layed out in the proper coordinate system:
The canvas origin is at the upper left, while the origin on paper is at the lower left.
This was not apparent until a non-symetric (vertical) layout was used.
