#43 Function pow requires include of math.h

[rockclimb]

In recent versions of GCC, the pow function, as used in src/filter/colorcorrectiongraphicsview.cpp, requires the include of <math.h>. The following patch achieves that, and continues to function with older GCC versions. I'd appreciate it if you could include the fix in the next release.
Thanks,
Andy</math.h>

This correction is necessary to get YASW working on MacOS High Sierra.
Otherwise a clean compile.
Thanks for this app
