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.

7c0b702e14 videoscale: Fix ARGB bilinear scaling 
Fixes #648548.  Orc generates bad code for
gst_videoscale_orc_resample_merge_bilinear_u32, so we'll use the
slightly slower two-stage process.  I'd fix Orc, but it's hard to
get excited about fixing a feature that I'm planning to deprecate
and replace.

030f639a8e android: make it ready for androgenizer 
Remove the android/ top dir
Fixe the Makefile.am to be androgenized

To build gstreamer for android we are now using androgenizer which generates the
needed Android.mk files.
Androgenizer can be found here:

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.

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.
