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.

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.

Fixes bug #615471.

33c490f4b9 videoscale: Add support for interlaced content
videoscale is not mixing content of two seperate fields anymore
and does scaling on every field separately.

Fixes bug #588761.

Add a 4-tap image scaler.  Theoretically looks much prettier.
The tap calculation could use some improvement.

from BaseTransform, implements a transform_caps. Removed dead code
including some PAR stuff that was never reached -- should probably
be added back somehow.

Original commit message from CVS:
* removal of //-style comments
* don't link plugins to core libs -- the versioning is done internally to the plugins with the plugin_info struct,
and symbol resolution is lazy, so we can always know if a plugin can be loaded by the plugin_info data. in theory.
