- At the moment using e.g. the thickness dialog and change from the default "1.0" to e.g. "21.3" triggers 4 recomputes. This takes a lot of time and is unnecessary. Qt offers therefore to disable keyboardTracking (and we use it already in the TechDraw workbench).
- also change the default draft angle from 1.5° to more common 10° and the step to 1° so that one can quickly get usual angles for drafts
