Misaligned table, missing FOURcc.

The printing of the visual id is awkward causing a misaligned header for the table.

     bf lv colorbuffer dp st  ms    vis   cav bi  renderable  supported
  id sz  l  r  g  b  a th cl ns b    id   eat nd gl es es2 vg surfaces 
---------------------------------------------------------------------
0x01 32  0 10 10 10  2  0  0  0 0 0x30335241--         y  y  y     win
0x02 32  0 10 10 10  2 16  0  0 0 0x30335241--         y  y  y     win

When printing out FOURcc instead, we get a neat table, with visual ID that is far easier to interpret:

     bf lv colorbuffer dp st  ms    vis   cav bi  renderable  supported
  id sz  l  r  g  b  a th cl ns b    id   eat nd gl es es2 vg surfaces 
---------------------------------------------------------------------
0x01 32  0 10 10 10  2  0  0  0 0  AR30--         y  y  y     win
0x02 32  0 10 10 10  2 16  0  0 0  AR30--         y  y  y     win

NOTE: In the example output above, AR30 stands for ALPHA Rgb 30bit colour. And is easier to interpret than a hex number.

NOTE: 'win' now lines up with 'supported surfaces.'

I will send an MR.
