Make it a bit easier to grasp the grouping when not
unnecessarily splitting comment blocks.
Additionally do not try to add lavu_video_display to itself, resolving
the following doxy warning:
warning: Refusing to add group lavu_video_display to itself
Fill it with AVStereo3D and AVDisplayMatrix documentation.
Apply the necessary changes to make verbatim code look good in doxygen.

- Check if av_display_rotation_get() gets the correct degrees
- Check if av_display_rotation_set() sets the correct matrix
- Check if av_display_matrix_flip() changes correct the matrix

* commit 'e4fe535d12f4f30df2dd672e30304af112a5a827':
mov: Write the display matrix in order
Conflicts:
libavformat/mov.c
libavutil/version.h
Merged-by: Michael Niedermayer <michaelni@gmx.at>
This will allow to copy the matrix as is and it is just cleaner to keep
the matrix in the same order specified by the mov standard (which is
also explicitly described in the documentation).
In order to preserve compatibility, flip the angle sign in the display API
av_display_rotation_set() and av_display_rotation_get(), and improve the
documentation mentioning the rotation direction.
Add AV_PKT_DATA_DISPLAYMATRIX and AV_FRAME_DATA_DISPLAYMATRIX as stream and
frame side data (respectively) to describe a display transformation matrix
for linear transformation operations on the decoded video.
Add functions to easily extract a rotation angle from a matrix and
conversely to setup a matrix for a given rotation angle.
