Chafa 1.14.0

[hpjansson]

This is a feature release with mostly practical improvements and bug fixes. It also adds a modest amount of new API in preparation for things to come.

• Removed ImageMagick loader support. Packagers can now remove this dependency.

• Polite mode is now off by default. The new default eliminates cursor flicker and makes the output more robust against unusual terminal settings. The old behavior can be restored with --polite on.

• Added image loaders for the AVIF and QOI formats. Thanks to @jerch for suggesting the latter.

• sRGB gamma is now handled correctly in scaling operations.

• New option: --passthrough=<auto|none|screen|tmux>. This allows passing graphics protocols like Sixels, iTerm and Kitty through a terminal multiplexer. It will be enabled automatically for Kitty, and can be enabled manually for other protocols with more limited support (thanks to @newyorkthink and @m040601).

• New option: --view-size=<WxH>. Specifies width and height of the viewport, overriding the detected terminal size (reported by @jaminthorns).

• New option: --fit-width. Fits images to the width of the viewport, allowing them to be taller than the viewport's height (thanks to @SuperDuperDeou).

• New option: --relative=<bool>. Enables relative cursor positioning. Useful if you've pre-positioned the cursor at a particular offset where you want frames to appear, but tends to make the output illegible in pagers, e.g. less -R (thanks to @Delgan and @AnonymouX47).

• New option: --exact-size=<auto|on|off>. Preserves the input pixel size when possible. Useful to avoid artifacts caused by resampling (reported by @ErrorNoInternet).

• New symbol selector: imported. This selects glyphs loaded with --glyph-file (reported by @clort81).

• MS Windows: Experimental support for ConHost output (-f conhost). This allows direct output on older versions of MS Windows (@oshaboy).

• Fontgen: Added a BDF font writer (@cdluminate).

• Fontgen: Cleanup and modernization (@cdluminate).

• The help text and manual page were overhauled for readability, and the API documentation now includes symbol indexes by version and deprecation status.

• Added a zsh completion script (@Freed-Wu).

• Installation methods added: Scoop (@LaunchLee) and Winget (@sitiom).

• CI: Ported to GitHub actions (@GuardKenzie).

• Bug fixes:
  "Unknown file format" when using stdin for AVIF on Linux #107 (found by @ndren).
  broken linking with libwebp-1.3.1 #152 (found by @vcunat).
  [unfiled] Fix make check with --without-tools (@sthibaul).
  [unfiled] Fix --duration not working well with still images (@Delgan).
  [unfiled] Fix sixel rendering of animations (@Delgan).
  [unfiled] Fix operator precedence in geometry calculation (@mjunix).
