fix for autoResize in dialog with button pane

I already posted this in the jQuery UI google group, but I figured it might be better to create a proper ticket. Here's what I posted on google groups:

I've got a dialog working, and I notice now that autoResize seems to

be working to make the div that is contained by my dialog fit to the

inside of the dialog properly...very nice. However, the problem I've

got now is that it doesn't account for the height of the button pane

if it is visible, so if I'm using the button pane, I have to disable

autoResize, and implement the same workaround I've been using with the

resize event...

So...here's my fix for the size method, which includes the button pane

in the height calculation (starting at line 240):

size: function() {

var container = this.uiDialogContainer,

titlebar = this.uiDialogTitlebar,

content = this.element,

buttonpane = this.uiDialogButtonPane;

tbMargin = parseInt(content.css('margin-top'),10) + parseInt(content.css('margin-bottom'),10),

lrMargin = parseInt(content.css('margin-left'),10) + parseInt(content.css('margin-right'),10);

content.height(container.height() - titlebar.outerHeight() - buttonpane.outerHeight() - tbMargin);

content.width(container.width() - lrMargin);

},
