Add an update indicator to the top right of client tabs; this is overlaid on top of the surface when the last update from the server was more than ~3s ago and if we expected it sooner than that. While making this work, I noticed that the exponential poll backoff had gotten broken in an earlier refactor; instead of a series of polls backing off slowly, we were aggressively running the backoff up to the max 30 second interval over the span of a few ms. This commit fixes up the backoff computation to only happen when we are ready to send a poll. refs: https://github.com/wez/wezterm/issues/127 |

Terminal Wizardry
This is a rust crate that provides a number of support functions for applications interested in either displaying data to a terminal or in building a terminal emulator.
It is currently in active development and subject to fairly wild sweeping changes.
Included functionality:
Surfacemodels a terminal display and its componentCells- Terminal attributes are aware of modern features such as True Color, Hyperlinks and will also support sixel and iterm style terminal graphics display.
Surfaces include a log ofChanges and an API for consuming and applying deltas. This is a powerful building block for synchronizing screen instances.- Escape sequence parser decodes inscrutable escape sequences and gives them semantic meaning, making the code that uses them clearer. The decoded escapes can be re-encoded, allowing applications to start with the semantic meaning and emit the appropriate escape sequence without embedding obscure binary bytes.
Capabilitiesallows probing for terminal capabilities that may not be included in the system terminfo database, and overriding them in an embedding application.Terminaltrait provides an abstraction over unix style ttys and Windows style console APIs.Changes fromSurfacecan be rendered toTerminals.Terminals allow decoding mouse and keyboard inputs in both blocking or non-blocking mode.Widgettrait allows composition of UI elements at a higher level.LineEditorimplements shell-like line editing functionality.

Testing via Wine:
sudo apt install gcc-mingw-w64-x86-64
rustup target add x86_64-pc-windows-gnu
cargo build --target=x86_64-pc-windows-gnu --example hello
Then, from an X session of some kind:
wineconsole cmd.exe
and from there you can launch the generated .exe files; they are found under target/x86_64-pc-windows-gnu/debug
