Form control size parameter
The testcases below apply the same style information to various form controls.
 - intrinsic width
 
- intrinsic width with a long nonbreakable text
 
-  a fixed width (20px)
Then various widths scenarios are tested inside table cells. This tests the maxElementWidth computation.
 - intrinsic width inside a auto width table
 
- intrinsic width inside a fixed width table cell which might be smaller than the intrinsic width of the control
 
- fixed width inside a auto width table
 
- fixed width inside a fixed width table cell which might be smaller than the intrinsic width of the control
 
- percentage width inside a auto width table
  
- percentage width inside a fixed width table cell which might be smaller than the intrinsic width of the control
  
- percentage width inside 100% wide table cell in a fixed width table.
