Strangely enough, that works the first time it displays, then after you
resize it again, the circle is way off the bottom right edge of the screen.
Not sure what's going on... I'm using lps-3.2.

Subject: Re: [Laszlo-dev] implementing non-rectangular masks in LZX
Here's a simplified version of what I got to work, which now that I look at
it is a wee bit more complicated that I remembered. You have to redraw the
shape whenever the size changes! This code tries to be lazy about that, only
resizing once after both the width and height change.
