This way the related file will be properly grouped with its
corresponding group like it's done in other places in the doxy.

Marvin Scholz 9570a833a0 avutil/display: consolidate group doxy
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:

Petru Rares Sincraian 124526ba1a Added a selftest to libavutil/display.c
- 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

Vittorio Giovara e4fe535d12 mov: Write the display matrix in order
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.

Vittorio Giovara bddd8cbf68 Add transformation matrix API.
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.
