61749c3649 Support older Pillow libraries 
Some distributions bundle older pillow, and we have
a way to support them.

left side.

169fd976ce Compensate for out of sync resize behavior 
During the async vnc behavior, a copy of the geometry variables
are used that are out of sync.

Workaround by forcing a resize again after the async tasks conclude.

6a90e1cc77 Implement a VNC to screenshot 
For Proxmox, since no convenient screenshot mechanism is available,
instead do vnc.

11939c4d57 Preserve aspect ratio if Pillow available 
Since we are controlling the scaling, we can manage
things more precisely and get the aspect ratio right.

8111a13554 Reuse image preprocessing for iterm and kitty 
Both can benefit, and lets iterm handling scale the way
we would like to scale it.

ef46b6cabd Take ownership of image scaling 
This fixes the imposed border being mangled, and also allows
Konsole to present decent looking scaling since it no longer
has to scale.

315d1d9b5e Change to common image from text for errors 
This allows easier management of rendering of text.

Also add a black and white border to make tiling more delineated.

d382bd5182 Provide cleaner recovery for image decode failure

recover from a condition, creating a stub 'screenshot' to
reflect the error.

a69113222f Fix positioning errors in tiled console display 
It turns out that specifying height and width explicitly
does not guarantee that the image protocols will actually fill
the specified space. Notably iterm will honor aspect ratio
(which is good), but leave the cursor where the image would
naturally leave it (which is difficult with relative positioning).

Previously, relative positioning was used as a workaround
for the fact that save/restore or any absolute positioning may
be fouled by incurring scroll.

To make cursor save/restore work, we determine the total rows and
print newlines enough to incur scroll and then move cursor back up.
This lets us use save/restore to ignore cursor movement by the image.

05ffc9da10 Constrain aspect ratio 
When parceling out the screen real estate, avoid either the height
or the width from getting way out of proportion.

Better to let screen be unused than abuse it to distort the
aspect ratio too much.

94af42031e Provide screenshot tiling with interval support 
Only for kitty graphics protocol.

Also, attempt to use pillow to convert, if available.  Kitty itself
needs this, Konsole can work either way.

It currently does not preserve aspect ratio, to do that
we pretty much need to do some work with pillow.

If we specify just the height, then ratio is preserved, but it won't
honor the designed bounding box on wide screenshots. Also
Konsole won't even honor just one scaling factor.

So the better thing would be to determine the aspect ratio, which
needs pillow.

e46b4ede6d Implement a CONFLUENT_IMAGE_PROTOCOL env variable 
This directs CLI with image output to use a preferred protocol.

This is retroactively applied to stats.

Currently we prefer kitty, as it seems to be the most widely supported.

Though some things only support iterm, so that's an option.

And some only support sixel, but the user has to be the one to
figure out adding pysixel dependency.
