top right design is not working as expected

Top right design is also visible in the content slides. It should be visible only in the TOC/Agenda/Section title slides. Two ways to tackle this issue:

1. Correct the behavior
2. Set the default behavior of \ScadsPresentationBackground link such that the design is scaled down to 0.5 using \scalebox{0.4}{image}. Then override this behavior for title slide by adding the same snippet for the design at original scale. at the end of \setTitleBodyTemplates at link.
