There is an interesting post about Emacs and how it threats grap= hical displays by D. Colascione An excerpt: "One simple approach to implementing redisplay is to just redraw all the fr= ames, windows, and buffers from scratch. This approach might be good enough= for a shitty 2016 video game like Nuclide or Eclipse, but not Emacs. Emacs was designed for much more constrained systems. Men were men, women w= ere women, and bandwidth was expensive. Consequently, Emacs tries very hard= to optimize redisplay." Since today bandwidth is not expensive, does this mean Emacs could move avay from the current redisplay to a simpler method which just redraws everything when required?
