[magick-developers] SVG: rotate image with a multiple of 90

[Thomas.Stegemann at materna.de]

In ImageMagick 6.3.5 (I have tested 6.3.5-4, 6.3.5-6, 6.3.5-8) images inside svgs are not rotated correctly.

In the following example the rectangle from "rect" will be rotated, but not the rectangle drawn with "image".
With old versions of ImageMagick (I have tested 6.3.3-10 and older versions) both rectangles are rotated.
Angles that are not a multiple of 90 are handled correct (I have checked 45 and 90.001).
