* Fixed a compile error on Mac
* Added QtUiTools to some more places
* Fixed a linker issue in the QtUiTools Python lib
* On occasion fixed a infinite recursion problem in the debugger
The recursion happened because by mistake I instantiated a
QApplication inside an in-application Python script. This
crashed the debugger due to infinite recursion. This is not
a real use case but to prevent similar issues, a recursion
sentinel was added.
* Removed QCoreApplication#notify from script bindings
Reasoning: "notify" made standalone scripts using QApplication and
QUiLoader virtually impossible.
Problem description:
- When a QApplication object is instantiated, e.g. in Python, the Qt binding
will install reimplementation hooks as the object may be dynamically
extended.
- A notify is virtual this means the *every* "notify" call in the application
is routed through the interpreter.
- For one thing this will slow down the application
- But as "notify" is called a zillion times this has more than this side effect.
- Specifically "notify" is called from within the QWidget constructor to
indicate a new widget. Then, if a QDialog for example is instatiated, it's
base class constructor will call "notify" when the object isn't ready yet.
- This has another severe side effect: as the object isn't ready yet, it gets
registered in the Python space with the wrong class and QDialog is not visible
as such.
To mitigate these problems, the most efficient solution is to disable "notify"
in general. There is hardly any use case in a script environment (in C++,
apart from hacking the only reasonable use case is exception handling, but
this does not apply to scripts). For providing the call functionality of
"notify" you should better use "postEvent" or "sendEvent" anyway.
So farewell QCoreApplication.notify ...
* Fixed python test for QtUiTools module
* Fixed UiTools test on Qt4 - QUiLoader needs an application object

* Implemented a backup scheme for the file writer.
* Also consider backup files when the writer fails.
* Removed test exception
* Added config option for number of backups.
* WIP: first part of fix - generation of hole cutlines
First problem was that hole cutlines got extended
over the whole length and sometimes lead to coincident
edges which are difficult to resolve for the polygon
cutter.
* Refined solution, fixed#718
- disabled elaborate hole insertion procedure for now as the
performance impact has to be assessed yet and the new scheme
will break many tests
- stricter rejection of ambiguous configurations in the polygon cutter
- fallback is boolean AND now since there is no need to re-invoke the
polygon cutter (we can't do so as we made it more strict).
Performance-wise we replace a merge by an AND step which may even be
faster the output is smaller and the polygon cutter does not need
to be re-invoked.
* Compatibility with other STLs
* In the MacPorts environment, Ruby 2.7 is used.
* Updated the build tools for Mac supporting Qt-5.15.2 from MacPorts.
* Updated the Ruby environment for BigSur and Catalina.
* To update the Mac DMG maker to support Big Sur.
* Updated the resource files for Mac DMGs.
* Fixed issue #704. TODO: replace algorithm by De Boor, check if accuracy is still maintained.
* Switch spline interpolation algorithm to De Boor for better numerical stability.
* Updated tests with DXF accuracy test, provide a warning for unsupported SPLINE types.
* Fixed a compiler warning
* Fixed#646 (crash on PCell Library "delete")
The issue was mainly caused by a "cleanup" call on
the library. Cleanup is supposed to remove excess
top level PCell variants. For libraries this is not
possible, as the library does not know which variants
are used and which are not.
In addition, some hardening against segfaults in
case of defect layouts has been applied.
* * Updated the build system for Mac
* Catalina env. uses Python 3.8 in MacPorts, Homebrew, and Anaconda3.
* Use Ruby 2.7 in MacPorts.
* Test build for macOS "Big Sur" (11.0) on Intel Mac "Catalina" (10.15.7).
* Updated the build system for macOS, including the future support for Big Sur (11.0)
