[Laszlo-dev] DHTML firebug profiler output of app startup

[Henry Minsky]

Here's something a little odd, when I did a profile run again, the top two
times (10% each)  were spent ingetTextDimension in a function with no
printed name but it said line 648 of the LFC:

var $4=this["__LZPropertyCache"]||LzCSSStyle.getPropertyCache(this);var
$6=$4[$2];if(typeof
$6=="string"&&$6.length>2&&$6.indexOf("0x")==0&&!isNaN($6)){

Which I think corresponds to this line in LzNode

  function __LZstyleBindAttribute(attr, prop, type) {
    // Inlined version of LzCSSStyle.getPropertyValueFor
    // Get the property cache for this node
    var pc = this['__LZPropertyCache'] || LzCSSStyle.getPropertyCache(this);
