fix condition logic for coef recalculation in SpatialSubtractiveNormalization (#1283)
* replace lon glong types with size_t
Work around bug in msvc compiler in win32 mode
* fix condition logic for coef recalculation in SpatialSubtractiveNormalization
Existing conditional expression always verified, resulting in overhead
as coeffcients were recalculated every time. Fix and simplify expression
by using chached input size.
