Adjustment handle reacts wrongly, if custom shape has a non default viewBox
A fix is in https://gerrit.libreoffice.org/69439

But I have no idea how to make a unit test for it. Perhaps you?

Here is what I would try:

- Crete a document manually that has a custom shape in it.

- Load that in a cppunit test.

- Get access to the underlying SdrObject, and downcast it to SdrObjCustomShape

- Create a EnhancedCustomShape2d manually, taking a reference to your
   SdrObjCustomShape.

- At that point you can call the SetHandleControllerPosition() function
   you modified in your code change and hopefully the AdjustmentValues
   key of the SdrObject's SdrCustomShapeGeometryItem would allow you to
   assert if the end result is good or bad.

This is really similar to what's done already in
svx/qa/unit/customshapes.cxx:267.

Thank you.
That works, at least locally. Let's see what Gerrit says.


I.e. if possible, I would try to not emulate a full actual mouse drag in
the test.

Not emulating a full actual mouse drag makes things a lot easier.

Kind regards
Regina
