Matches Gwyddion's i_datafield_to_field(tip, maxzero=TRUE, min=tip_min, step).
With tip_min = 0 (our tips are always shifted so min = 0) this simplifies to:
itip[y,x] = floor( (tip[y,x] − tip_max) / step )
itip[y,x] = floor( (tip[y,x] - tip_max) / step )

The tip "touches" the image at reference pixel (jxp+yc-jd, ixp+xc-id).
For the tip to be inside the surface (physically valid), the image
height at that reference pixel must be ≥ image_p − tip0[jd, id].
height at that reference pixel must be ≥ image_p - tip0[jd, id].

For tip pixel (ti, tj) and its reflected counterpart tip_flip[ti, tj]:
image[i, j] − tip_flip[ti, tj] − rsurf[sy, sx] ≈ 0
image[i, j] - tip_flip[ti, tj] - rsurf[sy, sx] ≈ 0
means that placing the tip so that tip pixel (ti, tj) touches the surface
at (sy, sx) exactly accounts for the measured height at image pixel (i, j).
The reflected tip is used because dilation/erosion use the tip flipped
180°. Coordinates:
sy = ti + i − ryc, sx = tj + j − rxc
where ryc = tyres−1−yc and rxc = txres−1−xc are the reflected-apex
sy = ti + i - ryc, sx = tj + j - rxc
where ryc = tyres-1-yc and rxc = txres-1-xc are the reflected-apex
offsets.
