wezterm: add experimental_bidi config option and very basic bidi This commit is larger than it appears to due fanout from threading through bidi parameters. The main changes are: * When clustering cells, add an additional phase to resolve embedding levels and further sub-divide a cluster based on the resolved bidi runs; this is where we get the direction for a run and this needs to be passed through to the shaper. * When doing bidi, the forced cluster boundary hack that we use to de-ligature when cursoring through text needs to be disabled, otherwise the cursor appears to push/rotate the text in that cluster when moving through it! We'll need to find a different way to handle shading the cursor that eliminates the original cursor/ligature/black issue. * In the shaper, the logic for coalescing unresolved runs for font fallback assumed LTR and needed to be adjusted to cluster RTL. That meant also computing a little index of codepoint lengths. * Added `experimental_bidi` boolean option that defaults to false. When enabled, it activates the bidi processing phase in clustering with a strong hint that the paragraph is LTR. This implementation is incomplete and/or wrong for a number of cases: * The config option should probably allow specifying the paragraph direction hint to use by default. * https://terminal-wg.pages.freedesktop.org/bidi/recommendation/paragraphs.html recommends that bidi be applied to logical lines, not physical lines (or really: ranges within physical lines) that we're doing at the moment * The paragraph direction hint should be overridden by cell attributes and other escapes; see 85a6b178cfddee94b3ddb39c26652bbd5a973666 and probably others. However, as of this commit, if you `experimental_bidi=true` then ``` echo This is RTL -> عربي فارسی bidi ``` (that text was sourced from: https://github.com/microsoft/terminal/issues/538#issuecomment-677017322) then wezterm will display the text in the same order as the text renders in Chrome for that github comment. ``` ;
