And correct decoration.

The idea behind this is to simplify the playlist_model and have a better SD control.

This conversion is always needed between mixer and output.

 * always use NEON VCVT
 * avoid pointless interlace/deinterlace in load/store

This patch adds the following keywords for skins developpers :
      - vlc.canRecord      (boolean / refers to can-record)
      - vlc.isRecording    (boolean / refers to record)
      - vlc.toggleRecord() (function / toggle recording)
      - vlc.nextFrame()    (function / next frame)

Sending one frame per block had way to high CPU overhead.

In some circumstances QTreeView does not behave properly if the column index 0 can hide/reappear.

Precisely, when column 0 is hidden and an item get's subitems, those subitems can not be D&D-ed.
If column 0 is then unhidden, trying to D&D the subitems will fail or result in unexpected behaviour.

So that tree branches appear on it.

Currently, detection is done at build time. Feel free to add run-time
detect if you know how.

While VFP/NEON do support floating point instructions, they appear to
be noticeably slower than fixed point.

You don't want it to be selected automatically.

This seems about twice as fast.

Else we won't have any lua scripts.
