Document wxGraphicsPath::AddArc() better.
The angles passed to it are measured clockwise from the horizontal axis, contrary to the usual mathematical convention so take care to mention this in the documentation. Closes #11112. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@61732 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
