Add ability to control size of a visualization's tooltip box and the tooltip font size about google-visualization-issues HOT 4 OPEN

Can someone please work on this issue.  I don't think this is a minor issue as the
tooltips are unreadable in many cases.

One workaround I have discovered is to use the "setOption" method in the options 
class to set some of the unexposed properties in the bar chart.

options.setOption("tooltipWidth", 400);
options.setOption("tooltipHeight", 200);

This makes the options balloon larger which in turn makes the text size somewhat more

acceptable.

A full list of such options can be found on this page

http://code.google.com/apis/visualization/documentation/gallery/barchart.html

Just in case the code I posted does not have the same effect for people, here is my

full options object

private Options createOptions() {
        Options options = Options.create();
        options.setHeight(250);
        options.setLegendBackgroundColor("FAFAFA");
        options.setBackgroundColor("#FAFAFA");
        //options.setOption("tooltipFontSize", 20);
        options.setOption("tooltipWidth", 400);
        options.setOption("tooltipHeight", 200);
        options.set3D(true);
        options.setMin(0);
        options.setMax(100);
        options.setTitleX("Percentage of attempts which resulted in passing 
the question");
        options.setStacked(true);
        return options;
    }

Sorry, in case it wasn't clear: the example above is for Bar Chart. The technique can

probably be applied to other visualizations, though.

@jmitchel : Thanks for the workaround, just verified that it works also with ColumnChart
also and in the js API. 
You just need to set 
'tooltipWidth':xxx,
'tooltipHeight':yyy,
'tooltipFontSize':ss
in the option list, no tooltip or tooltipTextStyle element opposite to what the documentation
implies.
