| 2016-07-12 | Improvements to gngr's table layouting 
  - table layout: support for row-groups.
 
  - 26 progressions
 
  - 4 pseudo-regressions (reference test now renders correctly)
 
  - table layout: default cellspacing is now 0 (+188)

| 2016-06-16 | Improvements to gngr layouting 
  - apply auto styles only for static elements (+9)
 
  - Background of root element should fall back to body element (+4)
 
  - Updated tests to latest nightly (gngr run, firefox run pending)
 
  - better table support
 
  - Recognize table rows and cells by display property, instead of tag names
 
  - Recognize more units for table cell width, height, etc  Progressions: 2  Semi-regressions: 6, caused by better rendering of tests
 
  - handle "auto" for top, bottom, left, right, width, height properties of absolute/fixed elements (+36)
 
  - Use previous render state as a fallback when computing font spec  Progressions: 20  Semi-regressions: 10. These are caused because:
    
      - the correct font computation results in larger fonts which causes more pixel differences
 
      - one of the test results in a scrollbar (because of the larger font).
 
     
   
  - Fixed background image offset calculation (+6)
 
  - relative positioning: handle 
auto values for left and top correctly (+3) 
  - Fit floats on same line whenever possible (+7)
 
  - honour 
font-size:0 (+39)
