Mouseover with stacked Bars not showing correct

[GoogleCodeExporter]

Using the following values in the Playground:

var options = {"bars": {"show": true, "stacked": true}, "mouse": {"track": 
true}};

The red line-markings that show which bar the mouseover is for, is shown for 
the "original" bar, not 
the stacked bar.

There are two problems here: 1) the hit detection is wrong (it is detecting 
based on the position of where the un-stacked bar would be); and 2) the drawing 
of the outline of the bar is in the wrong place (it is drawing an outline 
around where the un-stacked bar would be, not the stacked location). Someone 
please fix this; I want to use markers but can't for my stacked bar graphs.

Here is a patch that fixes this problem (or at least fixes the hit detection 
for stacked bar charts AND makes the outline drawn go from the x axis to the 
top of the selected bar)

I don't know if this is the most elegant way to do this but it works fine for 
me.

Also I based my code on the code for drawing stacked bar graphs.

Here is a replacement for my previous patch. It also draws the bottom of the 
highlighted section at the bottom of the stacked bar, not at the axis.

Not sure if it works for negative bars though (in fact pretty sure it doesn't).
