Ellipse Rotation Issue during conversion

[Vadoola]

Earlier while doing some testing on the test files in the libredwg github repo, there was a file with an ellipse. The ellipse comes through, but in the dxf it's rotated roughly 45 degrees, and in the elmt it's not. Part of the problem is rotation in QElements is only supported on text fields, so I can't even read in the rotation and add it in.

I'm marking this as upstream, because trying to draw a rotates ellipse using arc's would not be straight forward, and probably be ugly. Unless rotation support is added to ellipse elements upstream in QET, this bug probably won't get closed.
