wx.GraphicsPath and wx.GraphicsContext classes. They wrap GDI+ on
Windows, Cairo on wxGTK and CoreGraphics on OS X, and allow path-based
drawing with alpha-blending and anti-aliasing, and use a floating
-point cooridnant system. Currently they can only target drawing to
+point cooridnate system. Currently they can only target drawing to
windows, but other wx.DC backends are forthcoming. The APIs may
evolve a bit more before they are finalaized with the 2.8 release, but
there is enough there now to get a good feel for how things will work.
