enh(ui): apply SParameters stylesheet globally
Description
These changes apply the stylesheet from !795 (merged) globally. It can be enabled by setting the "touch_friendly"
application option to "true"
at configure time.
Closes #960 (closed)
How to test it?
- Build an application with touch_friendly=true, check that the style is applied.
- Build an application with touch_friendly=false, check that the style isn't applied.
- Check that all applications still look OK.
