025732d00f introduced deferred
window creation; the creation would get scheduled into the
spawn queue and then get run again a few milliseconds later
on the main thread.
For reasons that I don't understand, returning to the scheduler
loop to flush or otherwise process messages causes a wayland
protocol error.
Adjusting the notify routine to dispatch immediately if we're
already on the mux thread seems to resolve this.
While looking at this, I cleaned up a destruction order issue
with the opengl state that was then causing a segfault on shutdown.
I also removed a bit of dead paint related code that doesn't
appear to be needed any more.

This commit adds very basic first passes at representing the Pane
and GuiWindow types in lua script.
The `open-uri` event from 9397f2a2db
has been redefined to receive `(window, pane, uri)` parameters
instead of its prior very basic `uri` parameter.
A new key assignment `wezterm.action{EmitEvent="event-name"}` is
now available that allows a key binding assignment to emit an arbitrary
event, which in turn allows for triggering an arbitrary lua callback
in response to a key or mouse click.
`EmitEvent` passes the `(window, pane)` from the triggering window and
pane as parameters.
Here's a brief example:
```lua
local wezterm = require 'wezterm';
wezterm.on("my-thingy", function(window, pane)
local dims = pane:get_dimensions();
wezterm.log_error("did my thingy with window " .. window:window_id() ..
" pane " .. pane:pane_id() .. " " .. dims.cols .. "x" .. dims.viewport_rows);
window:perform_action("IncreaseFontSize", pane);
end)
return {
keys = {
{key="E", mods="CTRL", action=wezterm.action{EmitEvent="my-thingy"}},
}
}
```

Rather than having each call site add a window to the mux and then
call the front end to spawn a window, make the mux emit a signal
advising of a window spawn, and have the front end subscribe to
that signal.
