jst 378e366327 Replicate border instead of using a constant 
Constant border could lead to wrong values alpha values with certain
configurations.

jst dd1c157427 Include kernel boundary check 
Filter kernels should yield Zero if they are evaluted outside their
intended size. Though filterModel.Interpolate doesn't do this by design,
it's better to include it anyways.

Jason Summers cdbd68f34f Improve the way the new canvas size is calculated 
If both dimensions are given, always use those dimensions, avoiding roundoff
error.

If only one dimension is given, slightly prefer rounding the other dimension
up, to rounding it down.
