[Lazarus] TForm.GetFormImage is broken?

[Michael W. Vogel]

The method TWinControl.PaintTo doesn't refresh the RawImage.Data, like 
it is done in TRasterImage.Draw. It isn't only a issue for the method 
GetFormImage. I fixed it in revision 53790. As far as I can see, there 
are no additional calls done, as the needed one (e.g. 
TWin32WidgetSet.RawImage_FromBitmap is only called one time before 
saving to stream).

Hope, it works now as expected. If not, please report.
