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.

a3da634db6 video-format: improve unpack i420
unpack_i420 does not need extra code to handle odd widths, the orc code
already handles it fine.

0e3bfbd996 video-scale: combine adds when max_taps equals combine size
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.

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.

9396d843d6 video-blend: fix clipping of overlay images on the left
Fix clipping of images that are partially left of the video
surface, they would get clipped on the right side instead of
the left side, because the video unpack functions currently
ignore the x offset parameter. Work around that until that
is implemented.

9032c12e69 video-blend: fix blending of rectangles partially or fully outside of the video
In case of overlay being completely or partially outside
the video frame, the offset calculations are not right,
which resulted in the overlay not being displayed as
expected, or crashes due to invalid memory access.

When the overlay rectangle is completely outside,
we need not render the overlay at all.

For partial display of overlay rectangles, src_yoff
was not being calculated, hence it was always clipping
the bottom half of the overlay, By calculating the
src_yoff, now the overlay is clipped properly.
