7d261a147d Ensure scaling factors are calculated independently #452 
Fixes bug introduced in v0.15.0 where, if the shrink operation
rounded up along one dimension, it could then also round up the
reduce operation on the same axis, creating a small stretch effect.

62554b766f Add support for repeated/tiled overlay image (#443) 
USAGE: overlayWith('overlayimage.png', { tile: true, gravity: northwest} )
When using the tile option, the gravity option is applied to the extracted part of the tiled overlay image.

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.
