+Canvas Performance and ContentEditable
+---
+From the beginning of the [JavaScript Machines](/docs/about/) Project, I've always used an HTML5
+[Canvas](https://developer.mozilla.org/en-US/docs/Web/API/Canvas_API) object for both machine output
+and input.  It's the obvious choice for output, because the Canvas provides a 2D drawing API that's
+essential both for drawing bitmappped graphics and for faithfully rendering individual characters
+using the machine's original bitmapped fonts.
+
+The Canvas is perhaps a less obvious choice for input, but the theory was that by adding a
+"[contenteditable](https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/Content_Editable)" attribute
+to the Canvas object, the user could simply click (or tap) the Canvas to give it focus, and then all the
+usual *onkeydown*, *onkeyup*, and *onkeypress* event handlers would work as expected.  The advantage of
+this approach is that it eliminated the need for another on-screen control that would no serve no visual
+purpose.
+
+The "contenteditable" attribute had some issues, but mainly only on mobile devices, so I left those
+issues for another day.  For example, using PCjs on an Android device is problematic, in part because
+it doesn't honor the "contenteditable" attribute on a Canvas, but also because Android's built-in
+"soft keyboard" doesn't deliver any keys to the application until you press Enter.  So for now, you
+have to use PCjs machines that come with their own "soft keyboard".
+
+However, today I noticed an oddity with Safari on the desktop.  For the most part, Safari and Chrome
+perform comparably, and are generally the best browsers to use with PCjs.  Firefox used to be a great
+option a couple years ago, but ever since Mozilla started focusing heavily -- perhaps *too* heavily -- on
+[asm.js](http://asmjs.org/) performance, they seem to have fallen behind in overall performance.
+
+But I digress.  What I noticed in Safari was that text-scrolling in both DOS and OS/2 was significantly
+slower than Chrome.  This seemed very odd -- they should have been almost equally fast.  Then I made
+an important discovery: while the machine was scrolling, if I clicked on some other part of the page,
+taking focus *away* from the Canvas, scrolling dramatically sped up.  When I clicked on the Canvas
+again, it slowed way down again.
+
+Long story short: when I removed the "contenteditable" attribute from the Canvas, drawing performance
+was consistently fast.  The only problem, of course, is that I couldn't type anything into the machine.
+
+So I resurrected some old code I'd written that creates a transparent
+&lt;[textarea](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/textarea)&gt; on top of the Canvas,
+and now I use the &lt;textarea&gt; to provide all keyboard, mouse, and touch events (and pointer locking,
+for the handful of browsers that support it).
+
+That seemed to work well, until I tested Safari on an iPad, where I noticed a blinking cursor in the top
+left corner of the machine's screen; that is, the top left corner of the transparent &lt;textarea&gt;.  I tried
+all sorts of work-arounds suggested online -- setting the textarea's "color" attribute to "transparent",
+on the theory that the cursor used the same color, or setting the "cursor" attribute to "none" -- but none
+of those work-arounds seemed to, um, work.
+
+I had almost settled on adding iOS detection code, and reverting to the old Canvas input code for iOS only,
+when I noticed that even a Canvas on iOS displayed a blinking cursor -- it was just slightly less annoying
+because the cursor was flush with the left edge of the Canvas.  More importantly, it was also as tall as
+the full height of the Canvas.
+
+At this point, it seemed clear that iOS was trying to display the cursor based on what it believed the
+character width and line height to be: presumably zero for a Canvas.  So I switched back the transparent
+&lt;textarea&gt; again, set its "line-height" attribute to zero, and viola: no more blinking cursor.
+
+So that, in a nutshell, is why v1.16.2 of PCjs comes one day after v1.16.1: because I happened to noticed
+that drawing performance in desktop Safari was suffering, and that there was a fairly straightforward solution.
+
+Safari's behavior should probably be considered a bug, as it's probably doing something it shouldn't,
+like trying to account for an "invisible" blinking cursor.  Chrome certainly doesn't have this problem,
+so unless I was the only person in the world who used "contenteditable" Canvases, this is probably something
+Safari will want to fix.
