sc: lokit: fix wrong edit cursor coordinates for numeric cells

The cursor coordinates returned by editengine implementation is computed
with respect to document-visible-area in "display" hmm and not "print"
hmm. For numeric cells, the visible top-left is always non-zero, hence
triggering this incorrect "refpoint" subtraction to compute "relrect".

The fix is to calculate the correct "relrect" by subtracting the display
hmm version of "refpoint" from the edit cursor rectange and then convert
to twips.
