- Remove currently present magic numbers
- Hard type enums, so magic numbers can no longer be introduced. We don't want people to introduce magic numbers.
Convenience helpers function Tools::toStdString and Tools::fromStdString
were implemented for Qt4 or older to perform utf8 aware conversion as
QString::toStdString/QString::fromStdString were using toAscii/fromAscii
internally (see https://dreamswork.github.io/qt4/classQString.html).
Since Qt5 QString uses toUtf8/fromUTf8, which makes the helper functions
obsolete (see https://doc.qt.io/qt-5/qstring.html#fromStdString).
- section line convention label
- remove superfluous save/restore on changeEvent
- change default scrub count
- add preference for default symbol dir
- add preference for display of section cut line

* change default tolerance scale to 0.8
* the tolerance scale is directly applied, thus it must have non-italic label
* move tolerance scale to "Dimensions" tab
* move Fuzz settings to "Advanced" tab
* move Conventions to General tab since e.g. the projection angle is an important general setting
* add a note for the label font that this is also used for dimensions and that it there only has an effect for new ones
* use more useful step size of 0.1 for some scaling spinboxes
* sort UI fields in the C++ code to avoid doubled or missing entries (there were 2 doubled entries)
* uniform width of all preferences dialogs
* better alignment for the HLR dialog
Avoid to include ui generated header files within other header files but use forward declarations instead. This reduces dependencies between files and compile time considerably
