Interestingly, this screenshot of #xzoom is highlighting a bug in the border rendering -- I'll fix that soon. Heh!

#X11 #archaic application time!

#xzoom is a magnifier for X11, allowing for portions of windows or the desktop to be magnified.

#xzoom was originally written May 30th 1996, by Itai Nahshon.

Version 0.3 only supported 8-bit colour displays, but version 0.4 onward is maintained, and this supports upto 24-bit displays, and it's this version which most Linux distributions, and *BSD still ship to this day.

I've been using this program for years, and I find it really useful debugging window decorations in #fvwm3, as I can zoom in at detail to see how the rendering looks pixel-by-pixel.
