- Removed the meta=(MakeStructureDefaultValue= "1,1,1") from the FTransform struct because Unreal Header Tool is already capable to deduce that from the MakeTransform() default C++ prameter.
- Removed the meta=(Scale = "1,1,1") from MakeTransform UFUNCTION because that can be deduced by Unread Header Toold from the default C++ parameter.
Fixed Python code not invoking the a 'Make' function (declared with meta HasNativeMake on a USTRUCT) if no parameters were supplied to Python (ex. unreal.Transform() would not call the MakeTransform(...)).
- In most case, not calling the Make function worked as expected, but the Make function could implement side effects, so always honor it.
Resaved BP macro assets using MakeTransform() with the default values. The default values saved as string with the asset changed from "1,1,1" to "1.000000,1.000000,1.000000" and this triggered a BP Compiler warning.
The following tests were performed:
- In the Blueprint Editor, added a Make Transform node and ensured the default values for scale were (1, 1, 1)
- In the Blueprint Editor, created a User Defined Struct, added as a member a Transform, ensured the default values for the transform scale were (1, 1, 1)
- Added a Python regression unit tests to ensure unreal.Transform() takes the default scale value as (1, 1, 1) if the scale parameter is not provided.
- Created a Blueprint Macro Libraries with a Macro calling MakeTransform() with default parameters, saved it, applied the fix, got the warning, refreshed the node, resaved the macro and ensured the macro used the correct default scale.

PyObject ptr equality doesn't work for method objects as there's a new instance everytime.
Instead, compare the callables tp_call pointers and PyMethod_Self values for methods.

The following flags are now set when initializing the embedded Python interpreter:
- Py_IgnoreEnvironmentFlag - Ignore PYTHONPATH when calculating sys.path.
- Py_IsolatedFlag - Skip adding the user's site-packages directory to sys.path.
To counter the loss of PYTHONPATH, a new UE_PYTHONPATH environment variable is now available with the same rules as PYTHONPATH.
