           Summary: FILESAVE XLSX Line objects incorrectly saved after
                    creation
           Product: LibreOffice

Example file from Calc for further modification

This is a followup to bug 142914
When line objects are created and set to a rotation value between 225 degrees
and 315 and saved to XLSX they are incorrectly mirrored.
If the same line objects are saved to ODS, reloaded and then saved as XLSX then
the rotation is fine.

Steps to reproduce:
1.      Open the attached file, it contains some line objects
2.      Make copies of the objects and set a rotation value for them between
225 degrees and 315 degrees. On the screenshot I set 224, 225, 226 for blue
lines, 269, 270, 271 for green lines and 314, 315, 316 for orange lines.
3.      Save as ODS, then XLSX, reload to see the problem
4.      Open the ODS version, save as XLSX, to see it work correctly.

Actual results:
224 and 225 degrees becomes 224 and 225 (good)
226 degrees becomes 224
269 degrees becomes 181
270 degrees becomes 0
271 degrees becomes 359
314 degrees becomes 316
315 and 316 degrees becomes 315 and 316 (good)

Expected results:
Rotation values retained unchanged.
