Specify printing format of touch point co-ordinates.

Specify printing format of touch point co-ordinates.

Currently touch point co-ordinates are printed as floating point,
with no specified number of decimal places. This leads to inconsistent
and hard to read output. This patch prints touch point co-ordinates with
two decimal places of accuracy.

A follow up patch will re-enable
plugins/touch-events-details.html and
plugins/transformed-events.html,
and update their expectations.

dpranke, do you think this is reasonable?

Comparing floating point values in layout tests feels a little hairy - if you
have a better suggestion on how to approach this I'd love to hear it.

looks and sounds reasonable to me. There are a few places where we do look at a
few decimal places of precision.

lgtm.
