Please consider enabling `package-review-policy` on Emacs 31, and help reviewing package updates.

This will help to catch supply chain attacks on the Emacs package archive like this one:

Another fun example #emacs #org

I have implemented a new version of the Emacs canvas patch. Refreshing avoids redrawing or even checking the entire buffer. Only the single glyph where the canvas is attached as display property is redrawn.

I welcome help with testing or porting to other platforms than Cairo/Pgtk or X. @divyaranjan@mathstodon.xyz ported his Pale library to the new version of the canvas API, with good results.

Emacs doom scaling

The canvas has an original size of 320x200 and is scaled up by Cairo or XRENDER. Works better than expected.

@mekeor@mastodon.catgirl.cloud @tusharhero@mathstodon.xyz @divyaranjan@mathstodon.xyz As long as Gtk depends on Cairo, Emacs can continue to use it. But of course it is possible to replace it if necessary. The canvas intentionally only gives access to a simple pixel buffer. Right now it works with and without Cairo on X. I did not test other platforms.
