rotated rectangle causing svg-export problems

hello;

I am using corel-designer-x5.

I have dozens of corel files from a client (I am not the author).

Each of these files is exported from corel to svg, for the purpose of being used in a web page (via the Raphael-JS-svg library).

PROBLEM: it seems that any rectangles within the corel file that are rotated are causing various problems.

In the screenshot below you can see one of the problems. The left side is a screenshot from Corel itself, where I have zero's the angle on 2 of the rectangles, but the others I have left as the client gave them to me. The right screenshot is from my web browser, where the svg-from-corel is rendered into html-space via raphael-js-svg. And you can see the thick borders around the rotated rectangles.

These thick borders are not the only problem. The rotated rectangles are also causing transformation-matrix problems inside the web app.

Any suggestions? .... thanks.
