Image decoding is now done in a bg thread 
Continuing from the previous commit, this shifts:

* In-memory data -> temporary file
* Image decoding -> background thread

The background thread asynchronously decodes frames and
sends them to the render thread via a bounded channel.

While decoding frames, it writes them, uncompressed, to
a scratch file so that when the animation loops, it is
a very cheap operation to rewind and pull that data
from the file, without having to burn CPU to re-decode
the data from the start.

Memory usage is bounded to 4 uncompressed frames while
decoding, then 3 uncompressed frames (triple buffered)
while looping over the rest.

However, disk usage is N uncompressed frames.

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.
