Thanks for working on this -- but I'm still perplexed.

wx.ImageFromData + wx.BitmapFromImage.

should be creating at least one full extra copy of the data, and 
BitmapFromBuffer should be creating none. Unless wx.BitmapFromImage 
shares data between the Bitmap and Image when possible. But doesn't 
wx.ImageFrom data make a copy anyway?

So wx.BitmapFromBuffer should be the fastest, but a notable amount.

weird.
