bcb8068e27 docs: remove outdated and pointless 'Last reviewed' lines from docs 
They are very confusing for people, and more often than not
also just not very accurate. Seeing 'last reviewed: 2005' in
your docs is not very confidence-inspiring. Let's just remove
those comments.

fdfc6baf14 videoscale: fix adding borders when NV12 is used 
When the frame buffer is NV12 the borders are not added at all, fix that
and fill them to black.

Properties sharpen, sharpness, and envelope are only useful
near their default values.  Decrease ranges to avoid brokenness.

DAR on sink side now calculated with PAR on sink side
ratio of output width/height now calculated with inverse PAR
additional condition that borders are 0:0 for passthrough mode

7892e1e22f videoscale: fix 4-tap scaling for 64-bpp formats 
Fix invalid memory access caused by broken pointer arithmetic.

If we have a uint16_t *tmpbuf and add n * dest->stride to it, we
skip twice as much as we intended to because dest->stride is in
bytes and not in pixels. This made us write beyond the end of
our allocated temp buffer, and made the unit test crash.

63d1316c0f videoscale: fix negotiation after addition of new formats and methods 
Now that we no longer support all methods for all formats, we
need to cater for that in the transform function: we can't
transform formats not supported by the currently-selected
mehod.

make check, folks. It's da bomb.

a5f3d21723 videofilter: improve video filter 
Flesh out the video filter base class. Make it parse the input and output caps
and turn them into GstVideoInfo. Map buffers as video frames and pass them to
the transform functions.
This allows us to also implement the propose and decide_allocation vmethods.
Implement the transform size method as well.
Update subclasses with the new improvements.

8a9c4ed69f videofilter: implement propose_allocation

vmethod on some video filter elements so that we can also use video metadata and
bufferpools when not operating in passthrough mode.

4e38577b30 videoscale: Add modified Lanczos scaling method 
Adds a Lanczos-derived scaling method, which is rather slow, but very
high quality.  Adds a few properties that can be used to tune various
scaling properties: sharpness, sharpen, envelope, dither.  Not currently
Orcified, but was designed with that in mind.

ddce68a5c2 video: More video helper library improvements 
Make a new GstVideoFormatinfo structure that contains the specific information
related to a format such as the number of planes, components, subsampling,
pixel stride etc. The result is that we are now able to introduce the concept of
components again in the API.
Use tables to specify the formats and its properties.
Use macros to get information about the video format description.
Move code to set strides, offsets and size into one function.
Remove methods that are not handled with the structures.
Add methods to retrieve pointers and strides to the components in the video.
