Slight change in rounded rectangles

[KjellMorgenstern]

From Qt 6.5 to 6.10 , rendering of rounded rectangles slightly change.

Changes are highlighted in red.
Tiny font rendering changes are somewhat expected, since that also depends on the OS (font engine).

Using a separate Qt 6.5 svgviewer, with two rounded retangles. Second rectangle has width = 2r , so it is a circle.

With the Qt 6.5 test, the red and black roundings differ slightly:

And the same rendered with Qt 6.10

In Qt 6.10, the rounded corners of the rectangles exactly align, as expected.

While this is a slight change, I think it is more correct.

In absolute changes, even for the 1cm radius the total is less than 0.1mm , so below factory tolerances.
