Comment:
(In [20299]) Add a CPU based 'interlaced' filter that should synchronise
interlaced material to an interlaced display. Original patch from Paul
Gardiner with modifications for:-
- fix for bottom field first streams.
- fix flickering osd.
- reduced cpu consumption by avoiding redundant copies.
While this is the software based version of the OpenGL interlaced
'deinterlacer', the algorithm is slightly different (the OpenGL version
just displays one scaled field at a time) and I may align the 2 at a later
date if I get the chance to do more testing on different displays. This
version tested with 1080i50/60, 576i and 480i bottom field first all over
DVI/HDMI (i.e. no VGA to scart). Further potential CPU reductions with the
use of some MMX optimisations, although I don't see much point in making
this multi-threaded.
Closes #6391
