ce2d7b8efc Update pipeline.cc
In the upgrade to nan v2 that was part of v0.11.2 the baton values for blurSigma, sharpenFlat, and sharpenJagged were being cast to int32_t causing blur(sigma) and sharpen(radius, flat, jagged) to fail with "parameters out of range". This patch casts these baton values to doubles.
