tdf#157833 tdf#155692 sw: fix hit area to resize row/col

Fix 1) missing or too narrow hit area (tdf#157833),
and 2) not recognized click inside hit area (tdf#155692).

It was impossible or very hard to resize text table
columns and rows using the mouse:

1) Double arrow, i.e. "resize row/col" mouse pointer shows
the hit area of text table row/column borders. This was
missing or was very narrow with normal zoom, because of an
obsolete constant for low resolution displays.
Change this constant used in IsSame() with scale-dependent
values to support the same hit area on different zoom levels
and with different screen resolutions.

2) Especially on bigger zoom, "resize row/col" mouse pointer,
i. e. the visible hit area didn't guarantee drag & drop any
more because of too small hit area in pixels in the svruler
code base: clicking on not exactly center of the hit area
resulted selection of cells or the cell content instead of
drag & drop the border, violating WYSIWYG. Enlarge the default
1 pixel to 5 pixels to cover the whole hit area. Note:
only for resizing table borders inside the document, not on
the horizontal and vertical rulers.
