Doc: Usage added command for transparent pngs

Undocumented option to produce transparent png files
using lilypond command.

Even with @small example this line is too long (produces ugly black bars in PDF)
but lilypond command cannot be used with '/' for new lines.

So we have to list it on a single line.
