Post #297560

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 ported his Pale library to the new version of the canvas API, with good results.
