04e9a8dcc5 video-converter: improve matrix8 function 
Avoid using a constant.
Avoid doing saturated adds, results are not supposed to overflow here.
Rework the C backup function a little in preparation for custom backup
functions in ORC.

e2a693656b video-converter: fix chroma resampling check 
Decide if we need chroma resampling by checking if we have a progressive
or interlaced chroma resampler.

90eb93c2ef Don't compare booleans for equality to TRUE and FALSE 
TRUE is 1, but every other non-zero value is also considered true. Comparing
for equality with TRUE would only consider 1 but not the others.

afcc0b3c50 video-frame: Mapping a frame with inconsistent values between GstVideoMeta and GstVideoInfo is a bug 
It will cause the frame to be initialized with inconsistent values that then
later can cause crashes or any other kind of interesting and hard to debug
bugs.

57811331de video-blend: make use of x offset when unpacking overlay image pixels 
Now that it's implemented we can use it, which is a minor
optimisation when the image to overlay gets cropped on the
left.

60d18149e5 video-format: sprinkle some 'restrict' keywords in pack/unpack functions 
In cases where we just call orc directly this is somewhat
superfluous, but let's do it anyway for consistency. In
other cases the compiler can hopefully use this to optimise
memory access a little.

already handles it fine.

When the amount of pixels/lines matches the amount we can combine,
combine the adds and multiplies and do the scale as a separate
operation.

db304a446b video-converter: keep track of required temp lines 
Make a small object to hold a pool of allocated temp lines.
Keep track of how many temp lines each conversion stage needs and use
this to allocate just enough temp lines from the temp lines object. from
the temp lines object.

b9bee1af8c video-converter: handle mixed interlaced 
When dealing with mixed interlaced, setup a scaler and chroma-resampler
for both interlaced and progressive frames and switch between them
depending on the interlace mode of the input frame.

7b7270ecff video-resampler: add option to limits taps 
Add an option to limit the number of taps to use in automatic mode. The
problem is that for lanczos, we might use more taps than what we can
handle with the current precision.
Rework the other options a little to make it nicer to set defaults.

24989b53fc video-info: handle interlaced size correctly 
Refactor GstVideoInfo init, make function to set default colorimetry.
Call fill_planes after we configure the GstVideoInfo with parameters
from the caps.
The size of the chroma planes for interlaced vertically subsampled
formats needs to be rounded up to 2, we have 2 fields with each
the same anount of chroma lines.
