* [TD] remove unused headers
- also some sorting
- also improve readability by not using an abbreviation (we consistently don't abbreviate class names)
- correct interpretation of True vs Projected
- handle long subelement names in references
- fix "too small" value condition
- better error messages for bad dimension geometry
- separate validation, geometry and reference handling into
individual files
- improve 3d reference geometry handling
- eliminate duplicate dim creation code
- add Dimension reference repair dialog
- Refactor formatting out of DrawViewDimension
- move dimension repaint control to ViewProvider

also fix issue that tolerance could be set despite theoretically exact is true under some circumstances
also some wording improvements
also a minor fix to use 0.0 instead of DBL_MIN
as discussed here: https://forum.freecadweb.org/viewtopic.php?f=35&t=54218
when a value is theoretically exact it must not have a tolerance
This PR
* fixes this
* also fixes the bug that OverTolerance must not be negative if the tolerances are equal
- the setting "Standard and Style" only affects new dimensions, thus it must be italic
- fix bug that the Property 'LockPosition' appears for dimensions -> this is an option for views and thus must be hidden for dimensions
- since tolerances are in the vast majority fractions of a millimeter/inch, set its stepsize to 0.1
(I hope I did it right in handleChangedPropertyType.)
- fix inconsistent newlines in TaskBalloon.h
- improve wording for a heading
the common rule is that if a dimension has equal over- and undertolerance, they are output on the same line as the dimension concatenated using the ± character.
This PR does this.
Note that this is not just cosmetics, it is even standardized in the GD&T norms.
also:
* use one format specifier for tolerances since the norms don't allow a different format for the over- and the undertolerance
* some code optimizations like a self-explaining function name, remove unnecessary/outdated comments
