From c31f6222a111e3251a0afa6d3978865b41282880 Mon Sep 17 00:00:00 2001

Date: Tue, 3 May 2016 09:11:02 -0700
Subject: [PATCH] Added smoothing control to both PCjs and PC8080 (setting it
 to false should probably be the new default) It can be controlled with a new
 "smoothing" attribute on the <video> component and/or overridden with a
 "smoothing" URL parameter set to either "true" or "false"

 		If [Wikipedia](https://en.wikipedia.org/wiki/Enhanced_Graphics_Adapter) is correct that the IBM EGA
 		(presumably when paired with an IBM 5154 EGA monitor) has a "pixel aspect ratio" of 1:1.37 at its highest
