[webkit-dev] Metric unit measurements and on screen display

Because of the move to resolution independence on the Mac, I decided  
to see what would happen if I indicated a table using centimeters.  
What I found is that what was indicated was not what was displayed.  
The computer being used for this test is MacBook Pro (Core Duo), with  
the built in screen and using native resolution.

A test case is added at the end of the file. In the test case the  
table is specified to be 6cm wide, but is in reality 5.1cm wide. Is  
there something I am missing here, or is this something that should be  
flagged as a bug? What should the expectations be?

BTW I decided to compare this with Firefox 3 and Opera 9.5 and the  
results are not consistent:

   Opera 9.5 results in 6.9 cm
   Firefox 3 results in 6.9 cm


Test case:

<!DOCTYPE html
PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" >


<table style="border: 0.3mm solid rgb(170, 170, 170); width: 8cm;"  
     <tr><td class="numeric">8000</td><td class="numeric">151.52</ 
td><td class="numeric">227.682</td></tr>
     <tr class="even"><td class="numeric">8100</td><td  
class="numeric">153.414</td><td class="numeric">233.409</td></tr>
     <tr><td class="numeric">8200</td><td class="numeric">155.308</ 
td><td class="numeric">239.208</td></tr>
     <tr class="even"><td class="numeric">8300</td><td  
class="numeric">157.202</td><td class="numeric">245.078</td></tr>
