+ 	* src/TraceView.m (-mouseDown:, -savePDFImageToFile:),
+ 	src/TraceView.h:
+ 	Move PDF-saving code into a new action method, which is called by
+ 	-mouseDown. Add -acceptsFirstResponder and -acceptsFirstMouse:,
+ 	both of which unconditionally return YES.
+ 
+ 	* src/SpectrumView.m (-doRealFFTOnData:, -doWindowingOnData:),
+ 	src/SpectrumView.h:
+ 	Implemented several windowing functions (Bartlett, Blackman, Hamming,
+ 	Hann (aka Hanning), Welch). Change scaling again; FFT results are divided
+ 	by the area of the window function (which is N for the rectangular
+ 	window).

+ 
+ 	* src/SpectrumView.m (vsqrt(float*, int), updateDisplay:):
+ 	Fixed some more scaling bugs. FFT results are now being scaled by
+ 	1/N instead of 1/2; this seems to contradict Apple's vDSP docs but
+ 	gives the correct results (tested with TestSampler).
  
  	* src/SpectrumView.m (-doAccumulationOnData:, -doWindowingOnData:,
