Hello all,

I did some experiments with the latest POV-Ray 3.7 version available for 
MS-Windows platform (Beta 17) and a minimal GUI-Extension project that I 
wrote for testing purposes. I believe that something is broken in the 
GUI-Extension API.

POV-Ray 3.7 loads the GUI-Extension library normally but I can't get any 
information about the rendered pixels from POV-Ray, i.e. the 
GUI-Extension functions DisplayPlot(), DisplayPlotRect(), WinPrePixel(), 
WinPostPixel() and WinAssignPixel() are never called (I *do* initialize 
correctly the PointerBlock structure - everything works fine with 
POV-Ray 3.6)

It is also not possible to stop the render via the GUI-Extension API: 
POV-Ray receives the request and prints 'rendering stopped by GUI 
extension' in the message pane but the render does not stop (this is not 
a new problem, it happens with POV-Ray 3.6 too).
