Ari Koivula d7383ccb25 Change license to LGPL.
- Everyone who has contributed code to the project has been asked to license
  their contributions under LPGL and they have agreed.

- COPYING file changed to say LGPLv2.1 instead of GPLv2.

- GPL changed to LGPL in the header of every single file that a header and
  header added to the few that were missing one.

- Also.. Happy new year!

Ari Koivula d893a489d6 Fix mingw compilation issue.
strategies/avx2/dct-avx2.c:334:25: error: pasting "g_dct_16" and "[" does
not give a valid preprocessing token

- The [ is not part of the token so compilation failed on mingw GCC 4.9.1.
- Fixes #86.

Ari Lemmetti 85682c3b6a Removed unused transpose functions. 2014-10-03 11:39:31 +03:00
Ari Koivula f6272f06fc Unify signature for transform functions.
- Some used block, coeff and some src, dst. Now all signatures are const input
  and non-const output.

-Moved fast_forward_dst and fast_inverse_dst to DCT strategies
