Convenience function computes the structured coordinates for a point x[3]. The voxel is specified by the array ijk[3], and the parametric coordinates in the cell are specified with pcoords[3]. The function returns a 0 if the point x is outside of the volume, and a 1 if inside the volume.

Different ways to get the increments for moving around the data. incX is always returned with 0. incY is returned with the increment needed to move from the end of one X scanline of data to the start of the next line. incZ is filled in with the increment needed to move from the end of one image to the start of the next. The proper way to use these values is to for a loop over Z, Y, X, C, incrementing the pointer by 1 after each component. When the end of the component is reached, the pointer is set to the beginning of the next pixel, thus incX is properly set to 0. The first form of GetContinuousIncrements uses the active scalar field while the second form allows the scalar array to be passed in.

These are convenience methods for getting a pointer from any filed array. It is a start at expanding image filters to process any array (not just scalars).

Since various arrays have different number of components, the will have different increments.
Given how many pixel are required on a side for bounrary conditions (in bnds), the target extent to traverse, compute the internal extent (the extent for this ImageData that does nto suffer from any boundary conditions) and place it in intExt
