Wez Furlong 75c80ca322 bidi: feed reordered runs through to harfbuzz 
Two problems:

* Need reordered_runs method to populate ranges based on
  the reordered levels!
* Use reordered runs to get the *logical* bounds of those
  runs and pass those to harfbuzz.

Now the text is ordered correctly, but the rendering advances
by the wrong amount for the reordered clusters and looks bad
unless experimental_pixel_positioning=true.

wezterm-bidi - a pure Rust bidi implementation

This crate provides an implementation of the The Unicode Bidirectional Algorithm (UBA) in Rust.

This crate was developed for use in wezterm but does not depend on other code in wezterm.

The focus for this crate is conformance.

Status

This crate resolves embedding levels and can reorder line ranges.

The implementation conformant with 100% of the BidiTest.txt and BidiCharacterTest.txt test cases (approx 780,000 test cases).
