complete styles for cross browser CSS zoom

Question

I am finding it hard to get fully cross browser CSS zoom properties ..what I\'ve is only these

zoom: 2;
-moz-transform: scale(2);

If scripting is feasible then you can avoid both the collision of multiple supported zoom properties and the browser sniffing by using future-proof feature detection.
Note: I'm using jQuery here for convenience, but it could be written without it.

CSS:

.zoom {
    -moz-transform-origin: 0 0;
    -o-transform-origin: 0 0;
    -webkit-transform-origin: 0 0;
}

HTML:

Foobar

Script (One-Off Initialisation)

var strPropZoom = "zoom";
var blnPropZoomUseScale = false;

$(function() {
    var jqBody = $("body");

    // Determine the supported 'zoom' method
    switch (true) {
        case Boolean(jqBody.css("zoom"))              : break;
        case Boolean(jqBody.css("-moz-transform"))    : strPropNameZoom = "-moz-transform";    blnPropZoomUseScale = true; break;
        case Boolean(jqBody.css("-o-transform"))      : strPropNameZoom = "-o-transform";      blnPropZoomUseScale = true; break;
        case Boolean(jqBody.css("-webkit-transform")) : strPropNameZoom = "-webkit-transform"; blnPropZoomUseScale = true; break;
    }
})

Then when zooming is required simply invoke:

var intZoom = 2.5; // NB: This could be calculated depending on window dimensions
$(".mySelectorClass")
    .css(
        strPropZoom
        ,(blnPropZoomUseScale ? "scale(" + intZoom + ")" : intZoom)
    )
    .addClass("zoom");
