The nested blocks example:
The critical point here are the borders. As the comment says it is not
strictly speaking impossible: If I have a function to determine the
height of a face in pixels, I /could/ determine the height of a line,
programatically generate an PPM picture of the height of that line in
pixels, which is corresponds to a fraction of a vertical border line.
Doing this for each line I /could/ render the border. That's o.k. so
far. Then I have to update this whenever the user types something in
that paragraph. This seems to my like a reliable source for headaches.
But if you ask for impossibility, then you have a point here.
The table example:
The lines are not continous. The font sizes differ widely, but the
relative line-spacing doesn't.
Maybe I can demonstrate it with another piece of code. If you evaluate
the code at this URL (I should have thought of posting links earlier):
<URL: http://home.arcor.de/utis/table-example.el>
you'll see a buffer with three table cells in a row. The problem here:
all table cells have the same line-spacing in pixels; they should have
the same /relative/ line spacing. The middle cell, with the
smallest font size, should occupy much less vertical space than the
right column containing the largest font.
