Related: tdf#99315 BorderLinePrimitive2D: fix solid line primitive width
Regression from commit 2c62596cf264ef10749d8bfdb2bb2ebef2d98fbc
(fdo#75260: Correctly draw double lines for both Writer and Calc.,
2014-03-03), the problem was that when decomposing a double border line
promitive to solid line primitives (which happens for the legacy
"border" type, while both the Calc UI and Excel importer creates
"border-thin" ones), the decomposed inner line's height was larger than
the requested width.
As a result there was no gap between the polygon of the inner and the
outer line of the double border, looking like a non-double border.
The width of the outer border is still incorrect on the screen, though.
