orientation of arc segment is inverted upon saving and viewing in other software.

[Alvin Penner]

- running Windows XP, Inkscape r12676
- draw ellipse, set start = 90, end = 0
- note that open quadrant is at bottom right, as it previously was
- save as quad.svg, attached
- reload into Inkscape and note that image is the same as before.
- load into IE8, or Gimp, and the image is inverted, closed quadrant is at bottom right, the rest is open.

the flags in the arc element are being set differently than before. In current trunk the arc looks like:

d="m 261.42856,249.50504 a 115.71429,40 0 0 0 115.71429,-40 l -115.71429,0 z"

where the three direction determining flags are set at (0, 0, 0). In Inkscape 0.48.4 these flags would have been set at (0, 1, 1)

Reproduced with r12676 on OS X 10.7.5.

The test with archived builds shows:
- nor reproduced with rev <= 12627
- reproduced with rev >= 12629.
this change seems to have been introduced in
- Revision 12629: Further changes to SPEllipse.

Could you please try the second patch here: bug #1235504
This should fix it.

[Alvin Penner (apenner)]

sorry about that, I think I had previously applied only a portion of the patch because I was only interested in bbox.

anyways, yes, that works perfectly, thanks for the fix!

[Markus Engel (engelmarkus)]

Fixed in r12677.
