please add:

- global onpaint="" attribute which gets activated on a browser window repaint, with which it executes the code therein, such as a javascript function call.can call a js function that 
Example 1:
<div id="o" style="z-index:2;" onpaint="dopaint()">yahoo!</div>
<script>
function dopaint() {
    //move an element around
    var e=document.getElementById('o');
    var old=e.style.top.toString();
    //get rid of "px off of end and get value, add 4 mod document.height
    e.style.top = (((parseInt(old.substr(0,old.length)-2)+4)%document.height)+'px';
    //however, this code COULD be a problem, since it causes a repaint, 
    //and might be the kind of thing people try...
}
</script>
Example 2:
<p>document pixel area=<span id="t" onpaint="document.getElementById('t').innerHTML = document.width * document.height">????</span></p>

specifically, I needed the onpaint thing for working with a live rotating 4D <canvas></canvas> with support for red-blue 3D glasses someday I am trying to port from Java, which requires a paint hook do do animation using double-buffering as fast as it can. *IF* I can do double-buffering with canvas... this is for math folks who want to study 4D.


- window.onresize="" or global onresize="" attribute which activates when the browser document window is resized and executes the code in the string following the = sign. I don't know exactly in what to place this, whether as a DOM method/property (?) or if it's more appropriate for 

this comes in handy for games, but also for regular DHTML for element positioning and page sizing. many times a web developer will make a page hard-coded for certain screen sizes, but knowing the document width and height, and being able to rework the document for that could be handy for some. may get popular. I know I could use these both.

Example:
<!--form controls for 4D-->
<div id="o2" onresize="doresize()"><canvas id="c">4D canvas</canvas></div>
<script>
function doresize() {
    var formControls=document.getElementById('f').height;
    var nw=getElementById('nnavigation').width;
    var c=document.getElementById('c');
    c.width = document.width - nw; 
    c.height = document.viewport.height - formControls.height;
}
</script>
