We budget size based on the x_advance, which can be 1 pixel less
than the width of the glyph texture, so we could often end up
omitting the last character in "Launcher" or "default" in the
tab title or right status area.
This commit uses x_advance in both places.
Make the scrolling mostly independent of the active row; adjust
the top row when hitting the top/bottom edges of the display.
Mouse movement no longer changes the scroll position. Instead,
the wheel is used to scroll the list.

I generated nerdfonts_data.rs with this shell script; it uses `i_all.sh`
from the nerdfonts repo to get the base mapping:
```
source ./lib/i_all.sh
echo "//! Data mapping nerd font symbol names to their char codepoints"
echo "pub const NERD_FONT_GLYPHS: &[(&str, char)] = &["
for var in "${!i@}"; do
# trim 'i_' prefix
glyph_name=${var#*_}
glyph_char=${!var}
glyph_code=$(printf "%x" "'$glyph_char'")
echo "(\"$glyph_name\", '\u{$glyph_code}'), // $glyph_char"
done
echo "];"
```
Then intent is to use it in wezterm:
```
local wezterm = require 'wezterm'
wezterm.log_info(wezterm.nerdfonts.dev_mozilla)
```
Built using:
```
./FontForge-2020-11-07-21ad4a1-x86_64.AppImage --script $PWD/font-patcher "$PWD/src/unpatched-fonts/NerdFontsSymbolsOnly/NerdFontsSymbolsOnly Template 1000 em.ttf" --powerline --use-single-width-glyphs -out /tmp/nerd-fonts-out --fontawesome --fontawesomeextension --fontlinux --octicons --codicons --powersymbols --powerline --powerlineextra --mdi --weathericons

which is everything *except* Pomicons at the time of writing, pending
clarifications of its distribution license

It's a little ambiguous whether we should cancel the mode when moving
the cursor explicitly; I opted to do it when we move it due to newline
processing, or when its y position is changed.

This isn't ideal, but it is better than previously: we would
close the window and before the Drop impl had updated the
list of known windows, we'd try to re-assign that window
to another mux window in a different workspace, but it would
never appear because the window was closed.

Originally I had this the other way around but it was problematic
when considering things like maximized, font scaling and full screen
states.

Rather than just quitting the app and potentially silently killing off
a number of panes that might be running in other workspaces, we now
will pick one of those workspaces and activate it.
