I've created the patch to solve the former one.

In my investigate, if I understand correctly,
`Documentation/ly-example/granados.ly` has landscape settings.
So `granados.pdf` generated from `granados.ly` has `/Rotate 90`.

pdfTeX supports `/Rotate` in including PDFs.
Unfortunately, XeTeX does not support it.

If you give a look at this PDF:

you'll see some bugs:

some of them run out of the page


Well, this is not a new issue and depends on the quality of the images 
used.

I guess that we can ignore it.

- PDF page 10 is in landscape (while the document is a regular A4 of 
course)






This is the actual bug. I've investigated...
If you replace v2.19 with previous versions you can see that previous 
builds used PdfTex instead of Xetex and the image was compressed to fit 
on the vertical A4 sheet.


What's interesting is that my locally compiled web.pdf (with Xetex 
version 2017.03.30:1237) displays page 10 almost correctly, in that the 
page stays A4 vertical but the image is rotated 90° counter-clockwise. 
See attached the extracted page.

web.pdf on lilypond.org was built with a more recent version of Xetex.

Masamichi, any idea of what's going on?
