Description
Summary of the bug: when I try to resize using the bicubiclin algorithm, I just get an error, while others as sinc, lanczos or vanilla bicubic are working fine.
Also when trying to programmatically use SWS_BICUBLIN with sws_getCachedContext(), I get a C runtime exception.
Maybe, SWS_BICUBLIN has been removed from FFmpeg?
How to reproduce:

The option is called "bicublin", not "bicubiclin". If its spelled wrong, swscale won't recognize it and complain.

thanks heleppkes. The doc at http://www.ffmpeg.org/ffmpeg-scaler.html should be changed because it's telling us to use "bicubiclin"...

Please add a working command line (of the older FFmpeg version when this used to work) including console output if you want me to do the regression tests or tell us the offending commit if you do the regression test yourself.
