Detailed Description

The SvgTextShortCuts class.

Class to handle text property shortcuts generically.

Many text property shortcuts are about toggling/enabling a single property. Given there's a huge amount of them, it thus makes sense to generalize the actions by adding a special QVariant to them and using that QVariant to determine which property adjustment is at play.
