[PATCH 1/2] xrandr: Use more decimal places when printing various rates

[ville.syrjala at linux.intel.com]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Using just one decimal place for dotclock and refresh rates loses quite
a bit of information. When dealing with 60Hz vs. 59.94Hz refresh rate
modes for example, it's useful to see at least two decimal places. For
the dotclock in similar cases, three decimal places seems quite a bit
better than just one.
