22 This devolved into a rather empty class. The distinction between
23 various instances is made in the parser, which creates
24 midi/paper/bookpaper blocks depending on the keyword read.
26 The data structure is set up as recursive: the definitions not
27 supplied in paper are looked up in bookpaper. This is done through
28 the parent_ field of Output_def. However, such nesting is limited to
31 * first because the parser hard-codes the different types
34 * Second, because the prime benefit of multiple levels
35 (eg. bookpaper containing paper for a score, containing paper of a
36 \score embedded in \markup) requires scaling the Stencils (eg. the
37 one coming from score at markup level)
