+Notes for wxWidgets DrawEllipticArcRot(...)
+
+wxDCBase::DrawEllipticArcRot(...) draws a rotated elliptic arc or an ellipse.
+It uses wxDCBase::CalculateEllipticPoints(...) and wxDCBase::Rotate(...),
+which are also new.
+
+All methods are generic, so they can be implemented in wxDCBase.
+DoDrawEllipticArcRot(...) is virtual, so it can be called from deeper
+methods like (WinCE) wxDC::DoDrawArc(...).
+
+CalculateEllipticPoints(...) fills a given list of wxPoints with some points
+of an elliptic arc. The algorithm is pixel-based: In every row (in flat
+parts) or every column (in steep parts) only one pixel is calculated.
+Trigonometric calculation (sin, cos, tan, atan) is only done if the
+starting angle is not equal to the ending angle. The calculation of the
+pixels is done using simple arithmetic only and should perform not too
+bad even on devices without floating point processor. I didn't test this yet.
+
+Rotate(...) rotates a list of point pixel-based, you will see rounding errors.
+For instance: an ellipse rotated 180 degrees is drawn
+slightly different from the original.
+
+The points are then moved to an array and used to draw a polyline and/or polygon
+(with center added, the pie).
+The result looks quite similar to the native ellipse, only e few pixels differ.
+
+The performance on a desktop system (Athlon 1800, WinXP) is about 7 times
+slower as DrawEllipse(...), which calls the native API.
+An rotated ellipse outside the clipping region takes nearly the same time,
+while an native ellipse outside takes nearly no time to draw.
+
+If you draw an arc with this new method, you will see the starting and ending angles
+are calculated properly.
+If you use DrawEllipticArc(...), you will see they are only correct for circles
+and not properly calculated for ellipses.
