I'm adding this primarily to avoid repeatedly showing "No more
fallbacks" errors when moving the mouse over a terminal that contains
cells with no matching glyphs.
It has the nice side effect of changing the typical opengl tab render
time from ~2.9ms to ~1.3ms.
The opengl based render first clears the window to the background
color and then renders the cells over the top.
on macOS I noticed a weird lighter strip to the bottom and right of
the window and ran it down to the initial clear: our colors are SRGB
rather than plain RGB and the discrepancy from rendering SRGB as RGB
results in the color being made a brighter shade. This was less
noticeable for black backgrounds.
Remove a normalizing function that made assumptions based on the
keycaps that did not hold up when selecting Dvorak as an input
source. For example "CTRL-C" where `C` is the key with the C keycap
would send `CTRL-C` even when Dvorak was selected; it should send CTRL-J
in that layout.
I think with the other normalization that happens in the termwindow
layer we don't need this function any more.
We now display a list of tabs and allow selecting them with either
the up/down arrows or the k/j keys. Enter activates the selected
tab, Escape cancels the overlay.
An overlay is a little termwiz app that can be overlaid over the
content of a gui tab.
The intent is for these to provide the mechanism for meta operations;
listing all tabs in a long-form list and switching between them,
dropping into configuration or error log review and so on.
We now show a little status window when we're making a connection
for a remote mux domain.
This should make things feel slightly nicer if there is a connectivity
problem.

Rather than just a single attempt at each mechanism, let's allow up
to 3 loops, each time trying all supported mechanisms. This helps
for the case where the user makes a typo with their password, and
should also help for more complicated auth setups where succeeding
with one mechanism may not be sufficient.
While testing this out I noticed that were deferring closing the
OS level window until after the entire auth attempt, so I added
some logic to proactively close the prompt windows. In the longer
term I'd like all related prompts to render in the same window
for improved cognotive continuity.
