[oops, tex file attached this time]

Dear gang,

I am trying to create a grid background based on strut depth, so each line
of text lies right in between the top and bottom of the respective strut.
I borrowed some code from the wiki, and need help to solve the following
[and I'm no metapost guru...]:

1. Line 31, 2nd line of pdf: How can I keep \framed[align={r2l,middle}]
and get the interstrutline to still span the textwidth. In other words,
every strutline should be of textwidth, regardless of alignment

2. Compare pages 2 and 3: page 2 has extra space at the top, perhaps a
skipped line. How can I suppress that so that the first line always starts
at the top of the textblock?

3. On page 3: How can I control the continuation of the strutlines past
the final textline? What if, eg, I wanted to fill the rest of the page
with strutlines?

4. How can I change the width and color of the strutline itself?

5. I use \setuplayout[grid=on], but I'm not sure that guarantees a grid
... \start-\stoplinecorrection seems to give a different result.
[\showgrid seems broken so I can't directly compare]. Any tips to
guarantee a grid?

6. Is there a way to pass the interstrutline background to \framed [so I
don't have to type \start-\stopinterstrutline etc]?

This kind of gridded background is very common in eg, the Arabic-script
tradition, although it has many pedagogical and other uses as well. A
general strutline mechanism might make a good addition to the
distribution, or at least a nice module...

Any help or tips to improve this background will be greatly appreciated!

Best wishes
Idris
