epoger@google.com 46256ea736 Add to skdiff: test images for bitwise equality before testing for pixel-wise equality
- we now check for bitwise equality of files before bothering with pixel 
  comparisons (this will help with formats for which we don't have good
  decoders, like PDF)
- unparsable files are now reported as differing, unless they are bitwise equal
  (before, they were always reported as matching!)
- "largest area mismatch" is now based on same-size image pairs only;
  previously, if any image pairs had mismatching size, it was 100%
- removed repetitive "image size mismatch, so no diff to display" messages
- changed format of leftmost table cells to be more readable
