Here is again my 'second question'. So after when you do `M-x papyrus-demo`
(and scroll using the arrows) the 'gaps', which are the gray 'gaps' between
the pages,
have the height of the default `pixel-line-height`. Setting
`papyrus-gap-height` larger
will increase the gap size. However, setting `papyrus-gap-height` smaller
will not
decrease the gap size because it seems that the `line-pixel-height` is the
minimum.
I would expect the size could be smaller, so my question is why the minimum
size is
limited to be `line-pixel-height`...
