Comment 19 for bug 135319

brian-murray: excellent, from this edubuntu screen shot, I believe we can tell the following

  (0) theme: edubuntu-artwork
  (1) when: livecd integrity check
  (2) mode: 640x480
  (3) offset of throbber: x=212,y=352
  (4) width of throbber: 320
  (5) progress bar lies within defined text box area (so gets scrolled).

The off-centre is caused by:

  212 + 320 + 212 being bigger than 640.

The disjoint is caused by overlapping scrolled text area and progress bar.
