acsch incorrectly defined

[Zuzu-Typ]

So when working on a Python redistribution of GLM, I noticed an accidental recursion in reciprocal.inl.

[...]
// acsch
template<typename genType>
GLM_FUNC_QUALIFIER genType acsch(genType x)
{
	GLM_STATIC_ASSERT(std::numeric_limits<genType>::is_iec559, "'acsch' only accept floating-point values");
	return acsch(genType(1) / x);
}
[...]

it should be

return asinh(genType(1) / x);

This issue is fixed in master branch for GLM 0.9.9 release.

Thanks for reporting,
