+wxMSW: The window background is now only erased by default if the
+background colour or background mode has been changed. This better
+allows the default system themed behaviour to show through for
+uncustomized windows. Explicit support added for using the correct
+theme texture for wx.Notebook pages and their children.
+
+wx.Image: Added support for alpha channels in interpolated and
+non-interpolated image rotation. Added ConvertAlphaToMask helper
+method for turning shades of grey into shades of alpha and a colour.
+
+wxGTK2: Reimplemented DoDrawRotatedText() by way of a rotation of an
+alpha blended text bitmap. It would be better if Pango could draw
+directly into an wxImage (as FreeType can,) but that is for later...
+
+Added wrappers for wx.MediaCtrl.
