Fixes issue #19121 "dimension numbers placed lower than normal". Problem: QGCustomText has a new method `alignmentRect` which can optionally return a `tightBoundingRect` instead of the regular `boundingRect`. The `alignmentRect` is used for laying out the `QGIDatumLabel`, however QGraphicsItemGroup's `childrenBoundingRect` use the childrens' `boundingRect` and knows nothing of `alignmentRect`. The result is an improperly sized label and frame and miss alignment. Additionally `childrenBoundingRect` calculations includes hidden views, so even though the `m_tolTextOver` and `m_tolTextUnder` are hidden they still affect the bounding rect size. Solution: 1. Implement new method `QGIDatumLabel::tightBoundingRect` this calculates the bounding rect using the subview's `aligmentRect` if there is text in the custom text. 2. Use `tightBoundingRect` in place of `boundingRect` to for the drawing of arrows and the exact dim frames. 3. This PR acknowledges that there are some edge case fonts that while not clipped may not interface perfectly with arrows and the exact dimension frame. 4. Fix vertical alignment of `m_tolTextOver` / `m_tolTextUnder` 5. Incorporate PR Review comments

Overview
-
Freedom to build what you want FreeCAD is an open-source parametric 3D modeler made primarily to design real-life objects of any size. Parametric modeling allows you to easily modify your design by going back into your model history to change its parameters.
-
Create 3D from 2D and back FreeCAD lets you to sketch geometry constrained 2D shapes and use them as a base to build other objects. It contains many components to adjust dimensions or extract design details from 3D models to create high quality production-ready drawings.
-
Designed for your needs FreeCAD is designed to fit a wide range of uses including product design, mechanical engineering and architecture, whether you are a hobbyist, programmer, experienced CAD user, student or teacher.
-
Cross platform FreeCAD runs on Windows, macOS and Linux operating systems.
-
Underlying technology
- OpenCASCADE A powerful geometry kernel, the most important component of FreeCAD
- Coin3D library Open Inventor-compliant 3D scene representation model
- Python FreeCAD offers a broad Python API
- Qt Graphical user interface built with Qt
Installing
Precompiled packages for stable releases are available for Windows, macOS and Linux on the Releases page.
On most Linux distributions, FreeCAD is also directly installable from the software center application.
For development releases visit the weekly-builds page.
Other options are described on the wiki Download page.
Compiling
FreeCAD requires several dependencies to correctly compile for development and production builds. The following pages contain updated build instructions for their respective platforms:
