b3ff9c030f video-converter: align offsets to subsampling
Only apply an offset that is a multiple of the subsampling. To handle
arbitrary offsets in the future, we need to be able to chroma-resample
part of the borders.

49d909dabf video-scaler: add more ORC functions
Add the old ORC functions for nearest and linear. Label them as Low
quality because they are not as accurate but ORC lacks opcodes to
express this for now.

ca2bd1cc6b video-scaler: rename resampler to video-resampler
Prefix the resampler with video-. It we would like to reuse the
resampler for audio later, we can copy/move it and deprecate this
one.

daf20d5e09 video-scaler: remove color range argument
We just need to clip to the format limits, if there is extra headroom in
the range we can use that without problems.

implementation to deal with interlaced video as well as horizontal and
vertical scaling functions.

549bdd4ece video-converter: rework the generic converter function
Use a LineCache object to track and process lines between unpack,
upsample, convert, downsample and pack stages. This simplifies the
main core processing function a lot and allows for future additions
easily.

Add support for interlaced formats in chroma up and downsampling.

2847a8108c video-blend: segfault when xpos >= video size
When the xpos is given as greater than or equal to the video size,
we get a segfault, due to improper condition.
Hence adding proper conditions.

3f5b9c4c8b videoblend: Avoid assigning a negative value to a guint
There are some few but certain conditions where it is possible for the
dest_width to be smaller than x. So we check this before assigning a negative
value to src_width, which is a unsigned and would be promoted to a number that
can segfault videoblend.

7b428a8bcb videoencoder: Stop storing if we received EOS
This was never reset when going from PAUSED->READY and resulted
in encoders being not reusable after EOS. They just rejected any
buffer because they received EOS in their previous life.

The flag wasn't used anywhere except for rejecting buffers after
EOS, and this is now handled by GstPad directly.

b2fd20c416 video: move videoconvert code to video library
Move the conversion code used in videoconvert to the video library
and expose a simple but generic API to do arbitrary conversion. It can
currently do colorspace conversion but the plan is to add videoscale to
it as well.
