Class lsst::afw::math::BilinearWarpingKernel::BilinearFunction1

class BilinearFunction1 : public lsst::afw::math::Function1<Kernel::Pixel>

1-dimensional bilinear interpolation function.

Optimized for bilinear warping so only accepts two values: 0 and 1 (which is why it defined in the BilinearWarpingKernel class instead of being made available as a standalone function).
