This makes it possible to configure wezterm to eg: triple click
on command input (or output) to select the entire input or output
without messing around trying to find the bounds.
The docs have an example of how to configure this; it requires
setting up shell integration to define the appropriate semantic
zones.
9892b16d40 adjusted how the text
colors are produced; it resulted in some ugly dark edges, especially
on lighter backgrounds.
This commit routes that tint via an alpha compositing helper which
produces smoother edges.

This commit more cleanly separates the load from the render flags,
and fixes up the render call; at some point this got messed up such
that we'd never end up with freetype returning subpixel format data
(LCD) and instead we'd only ever get grayscale data.
With that fixed, it's apparent that the colorization of the glyph
data was wonky in the shader so this commit also cleans this up.

If you have a primary font whose height is a bit more than double the
width then a double-wide emoji would be scaled to a bit more than two
cells in width.
This commit adjust the glyph scaling to check both the x and y scaling
to ensure that they glyph fits within the appropriate number of cells.
This has the consequence of rendering eg: the heart emoji smaller than
in previous versions; the heart glyph is typically square but the
broadly used concept of width for the heart unicode character is a
single cell. Previously we'd incorrectly render this double wide.
I'm not sure of a way to do better than we are right now because
freetype doesn't provide much help for scaling this kind of bitmap
font AFAICS.

There were two problems:
* It was using an old code path that didn't even try to resolve the cwd
* The NewWindow code path would "forget" the originating window and then
fail to resolve the current pane + path from the new, empty window
that it is building.

Adds some supporting methods for computing the `SemanticZone`s
in the display and a key assignment that allows scrolling the
viewport to jump to the next/prev Prompt zone.

Needed to re-order a couple of things to match recent changes.
Also: don't hard fail if the ssh server rejects a setenv request,
just log the error instead.
A consequence of reducing the initial texture size is that for
larger starting font sizes it isn't big enough. We need to make
a couple of passes to determine the required size, so that's
what this commit does.

This commit moves a bunch of stuff around such that `wezterm` is now a
lighter-weight executable that knows how to spawn the gui, talk to
the mux or emit some escape sequences for imgcat.
The gui portion has been moved into `wezterm-gui`, a separate executable
that doesn't know about the CLI or imgcat functionality.
Importantly, `wezterm.exe` is no longer a window subsystem executable
on windows, which makes interactions such as `wezterm -h` feel more
natural when spawned from `cmd`, and should allow
`type foo.png | wezterm imgcat` to work as expected.
That said, I've only tested this on linux so far, and there's a good
chance that something mac or windows specific is broken by this
change and will need fixing up.
