c33bbc8f23 clamp scroll values rather than asserting 
I've been looking at https://gitlab.freedesktop.org/terminal-wg/esctest/tree/master
to verify some behaviors and found that it would send out of range
values that would cause wezterm to panic.  Rather than panic, just
clamp.

2c32eb9337 recognize window management related CSI 
These were showing up as unrecognized sequences on my mac, and I
wondered what they were.  We now parse them and do nothing with
them, other than print out the parsed form :)

1a883a40e9 use vte with larger OSC buffer support 
I wanted to see how much work remains to enable iterm2 image
display; one of the blockers was a limit in the size of the
buffer in the vte crate, which has been removed in my fork
of vte.

As part of testing our ability to absorb that data, I found
a couple of issues with applying the image cells to the display,
so this commit also takes care of that.

We still don't have code to connect the cell image data to the
opengl render layer.

f261f079f7 lift clipboard hotkeys up to gui layer 
My original idea was that I would centralize of the key binding
logic in the terminalstate, but this places a bit of a burden on
the TerminalHost portion of the interface.

In particular: when running a multiplexer server we may be headless
or have multiple heads.  In that scenario we want the terminal
to be backed by a virtualized screen, and that means removing
the direct callback to access eg: the host clipboard.  This
diff is the first of a couple that have the goal of removing
those sorts of dependencies.

d7b55382b4 big initial mux change 
This is an unfortunately large diff that:

* Separates Tab ownership from TerminalWindow
* Introduces a Mux container for all of the tabs in the application,
  across all windows
* Moves ownership of processing pty responses to the mux; it sets
  up and has logic to process data for the ptys and apply to the
  tabs

I've moved the logic for processing new tab and new window hotkeys
to the TerminalWindow's themselves as we need some context to
associate the tab with the right window and to create a new window.

I think that will simplify and allow unifying more code.

184befae09 adjust double-click selection class 
previously this just used unicode word segmentation rules, but that
is insufficient for most technical users.

Change this to look for sequences that are non-whitespace and not
enclosed by bracket/quote delimiters.  This allows selecting file names
with a double click, which was my main issue.

42fb687759 more fun with keyboard input with glutin/winit 
There isn't really any reliable consistency in the virtual_keycodes
being set for simple keys or shifted keys, so we need to go all in
and add our own scancode processing as a fall back.

This makes it even harder to process unicode input, particularly
because we have no idea whether a ReceivedCharacter event will
follow.

4092796db3 Fix an issue where the background color rendered gray instead of black 
When using the default monospace font on ubuntu (typicaly
DejaVuSansMono), the texture atlas would end up the bottom left pixel
being a shade of gray.

Since we were using (0,0) coords for whitespace cells, all whitespace
cells would appear shaded gray.

We now reserve a black pixel in the bottom left of the underline texture
and switch to that for whitespace instead.

I added Debug support to the ColorPalette while tracking this down,
and figured that I might as well keep it.

279b2018fd Render cursor and selection for resized lines 
If the user enlarges the terminal we can have regions of the vertex
buffer that have colors that default to alpha channel 0.  This is
normally fine but breaks rendering of the cursor and the selection;
those attributes are out of band from the normal cell attributes,
especially for whitespace cells, so we need to handle those in
the degenerate case at the end of a line render.

Refactor the code that computes the cursor and selection colors
so that we can call it and use it in both places.

21f0e3fd98 Recognize clicks on hyperlinks 
There's plumbing for handling these events in the TerminalHost
trait, but we don't do anything beyond printing them at the moment.

b6aa2cffea make hyperlinks show underlined on hover 
Adds some plumbing to track the current mouse position and
extract the hyperlink from the cell that is being hovered over.

We render those cells with underline, possibly in a different color.

We don't yet do anything on click.

7ad2468937 hide AnswerBack from the public interface 
This felt a bit repeatey and it pre-dated the TerminalHost trait.
I'd like to remove it completely but there are some frustrating and
fiddly lifetime concerns with mutable TerminalHost reference so I'm
hiding it from the public interface and bridging it the answerback
stream into the host at the bottom of the advance_bytes method for
now.

This enables selecting an italic font when the cell is italic,

This runs a little hot on the CPU so there's probably some caching and

4c8e3ffd75 improve clustering and cursor rendering 
We weren't quite right with handling the cursor around double-width
characters.  We're now a bit more robust at this because we're
clustering and taking pains to consider the printable width of the
cell as well as the width of the shaped (eg: with contextual ligatures)
glyph.

There may still be issues with contextual ligatures of length 3,
but I haven't managed to nail down exactly the issue yet.
