request addition of inverse hyperbolic function to fx

[fmw42]

This is not a high priority request as there are workarounds. But for completeness and for a test I was trying to do, I would like to request when convenient and not too hard to do, and if the c libraries support them, the addition of the inverse (arc) hyperbolic functions: asinh, acosh, atanh to the list of functions supported by -fx.

Thanks.

We'll have support for these functions in ImageMagick 6.7.1-1 Beta by sometime tomorrow.

thanks.

Forgive me if I'm wrong, but I was just trying to build this in Visual C++ 2010 SP1, and the acosh, atanh, and asinh don't exist in math.h. This has broken our ability to build the CORE_magick.dll.

Also, CORE_png and IN_MOD_png appear to require .h files that aren't in the Windows .zip (i.e. - pngpriv.h).

I hope this is an oversight in the .zip file and not some major issue I'm having.

Thanks!
