Our positionning of the scan line (ligne de codage) was possibly wrong
depending on wkhtmltopdf.
In eg. chromium the font is configurable exactly but in wkhtmltopdf it
seems there is bigger limitation on giving eg. a decimal pixel number.
But this was necessary to have the same character positionning than
expected in BVR, and this line is read by scanner and must match.
This change:
- have an absolute positionning for each character in the scan line
- add two parameters "ISR scan line horizontal/vertical offset" that
will move the scan line to the choosen distance.
- changes some other CSS value to match better the ISR documents on
accounting on differences between wkhtmltopdf 0.1.2.1 and 0.1.4.1
- remove currency which should be on the BVR background.
