Wrong/misleading images

[Thomas Morley]

Hi,

at https://lilypond.org/macos-x.html
the images
./Documentation/pictures/Learning_Macos_welcome.png
./Documentation/pictures/Learning_Macos_pdf_output.png
are not longer correct.

The first one is intended to show the code for the scale demonstrated
in the latter.
Alas, the meaning of \relative { ... }, i.e.without reference pitch,
changed somewhere in 2.17.x.
So nowadays, the scale would come out one octave below.
Likely both images should be replaced.

Probably the same for https://lilypond.org/windows.html

Cheers,
  Harm
