Wez Furlong d59898987a gui: fix lost sync with the cell position in the renderer
If a cell contained a ligature, the math used to track where the
next quad was going to be placed could lose consistency with
the cluster/shaping information and result in offset glyphs.

This was most noticeable to me in tab titles in the tab bar;
my shell dotfiles append `-- something` to the title when a
command is launched, and the `--` is a ligature in my font.

I think I've also seen this mess up positioning in the notcurses
demo as well.

The solution is to take the cluster initial cell index rather
than trying to reverse engineer it from incomplete info.

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:

  • Surface models a terminal display and its component Cells
  • 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 of Changes 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.
  • Capabilities allows probing for terminal capabilities that may not be included in the system terminfo database, and overriding them in an embedding application.
  • Terminal trait provides an abstraction over unix style ttys and Windows style console APIs. Changes from Surface can be rendered to Terminals. Terminals allow decoding mouse and keyboard inputs in both blocking or non-blocking mode.
  • Widget trait allows composition of UI elements at a higher level.
  • LineEditor implements shell-like line editing functionality.

Windows Support

Termwiz understands how to work with both the legacy console APIs and the new PTY and virtual terminal features available in Windows 10, allowing for true color terminal applications on Windows 10.
