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.

91ed9290b8 videoscale: Fix assertion on caps fixation 
When fixating caps, from_par should always be initialized
with a fixed value.

In case the fixation is from src to sink pad it was setting
the from par (srcpad par) to a fraction range, this patch initializes
it to 1/1, based on the assumption that missing PAR is 1/1.

This reverts commit b2051090b4.

Fixes the build again until someone pushes the regenerated .c/.h
files too.

4d757a29ee videoscale: Only set the PAR if the caps already had a PAR 
Otherwise we're producing different caps and basetransform thinks that it
can't passthrough buffer allocations, etc.

In 0.11 all video caps really should have the PAR set...

58c77eb1b4 videoscale: Remove interlaced scaling again 
This behaviour was not preferred and caused visible image quality
degradations. The real solution would be, to apply a real
deinterlacing filter before scaling the frames.

Original commit message from CVS:
* gst/videoscale/gstvideoscale.c: (gst_video_scale_transform_caps):
Prefer the given format if it contains something stricter than [1,MAX]
for height or width and only put a structure that requires rescaling
as second. This makes it possible to use videoscale in pipelines where
the source can actually produce the wanted height/width but usually
selects a different one from the requested.
