WebView capabilities review

[Felix Bembrick]

I have noticed something curious.

When I run the impact.js demo that Klaus posted a link to I see a very
smooth animation.  The curious part is that on this same machine I see
noticeable flicker and jittering when I run even the most simple JavaFX
animation and have never seen one that performs as smoothly as the
impact.js demo within WebView.  Also, the impact.js demo runs very smoothly
even when I run the WebView maximised.

OK, so now I know that it can't be the actual graphics hardware or driver
that cause JavaFX animations to flicker and clearly JavaFX *can* render
animated content without jittering so why then do simple animations (such
as those from Ensemble) perform so poorly?
