[x264-devel] Bug found in --intra-refresh

[Alain Champenois]

Hi Jason,

You missed removing I_PRED_4x4_HD mode which also make use of the top-right pixels:

-        {I_PRED_4x4_H, I_PRED_4x4_HD, I_PRED_4x4_HU, -1, -1, -1, -1, -1},
+        {I_PRED_4x4_H, I_PRED_4x4_HU, -1, -1, -1, -1, -1},

With this modification, my qualifications tests are now passing and intra refresh 
properly remove all corruption.

  Alain
  PS: After reviewing the code, the top-right restrictions are already only 
      applied for the right-most intra column, so the code is already optimal.
