* Removed DefaultAnnoDisplayMode. This will become a fine-tuning preference.
* Removed HatchPatternResolution as it was not used.
* Added DefaultAnnoLineColor and DefaultAnnoLineWidth. These will be implemented in other parts of the Draft code in later PRs.
* DisplayMode controlled by new pref DefaultAnnoDisplayMode. This replaces the old dimstyle pref.
* LineSpacing pref is now used when creating annotations. Will be added to prefs ui later.
* format_object no longer changes FontSize as this conflicted with the height parameter in the make_text function.
* make_text function updated.
Additionally:
* Added the DimShowLine preference. Layout of the tab will be updated later.
* Improved handling of DraftAnnotationScale preference: catch division by zero and use it for the default anno style.
