[PATCH v2] emacs: add notmuch-logo.svg and use it in emacs mua on graphic displays

[Tomi Ollila]

emacs/notmuch-logo.svg is handcrafted scalable vector graphics version
of the notmuch logo.

Emacs on graphic displays render this image four times in size compared
to the emacs/notmuch-logo.png, and the image is much sharper.

The rendered image size, 100x110 pixels, fits reasonably well with
text shown in various font sizes.

Scaling the image -- if desired -- may come in the future. For now
this is improvement on how the logo looked in notmuch-hello window.
---

In this version 2, of id:20211101225336.29070-1-tomi.ollila@iki.fi.

Dropped dimensions from 200x220 to 100x110; scaling in emacs is nontrivial;
imagemagick can do it but then it renders background white which looks bad
when using "dark" mode. (press '+' and '-' on top of the image and see
background going white (in this case it also scales the pixel image, 
does not re-render svg).

Spent a bit of time with svg.el -- then noticed it does not support
translate, rotate nor scale. In order to use that I would have to
calculate the final pixels (and if we desired scaling, then dynamically
counting dimensions and pixel endpoints...)

If scaling does not improve in (future) emaces, one option could be
to parse the xml, change image dimensions, add scale (and background
rectangle) nodes, then write xml to string and load that image
(whether that works or not, I don't know -- or if that is good idea)

I wish it was possible to scale in units relative to text size. For me
with default settings it looks a bit big (see attached). Anyway, I can
live with this (not least since I don't normally display the logo).

Anyone else want to chime in before I apply this change?

Nice font, is that 20 pixels in height ? (and what font is it ?)

> Anyone else want to chime in before I apply this change?

I personally tried with 12x25 sized font (xrandr tells 1920x1200, 
294mm x 165mm so what is that in dpi...) -- and it could be that
majority of users uses smaller font so it could look a bit tall.

Let's wait for a while for more comments.

In the meanwhile, after sending the patch email, I noticed that the
.png is 50x58 in size and .svg 110x100 (I accidentally swapped 
dimensions). So now I tried to drop 10 pixels from bottom (making
it 100x100) which makes it look a bit more like the original. 

The modified image is available below; the html "decoration" is 
for your entertainment: copy the whole content into a file.html, 
open file://$PWD/file.html in your web browser -- if web browser
is firefox, ctrl-+ and ctrl-- scales the image...

I use "DejaVu Sans Mono-normal-normal-normal-*-17-*-*-*-m-0-iso10646-1",
but I'm not sure what that is in pixels. Some random web types claim
that it is more like 23px @ 96 dpi.

Agreed, it's not too urgent. Although apparently the cool kids are
annoyed the old logo does not work with their themes.

Hello David, 

Looks good to me. The old logo always felt a bit small to me anyway. 🧐😜

Cheers,
