We had code on the window to reset the default-font-size property to the
default from the renderer.
For the Qt backend, the PopupWindow being their own Window, this code
was activated also for the PopupWindow's hidden default-font-size
property, which caused all PopupWindow's font to not follow the
default-font-size
Fixes#8855
The struct held provides access to the design metrics of the font scaled
to the font pixel size used by the element.
ChangeLog: Slint Language: Added font-metrics property to `Text` and `TextInput`.
Closes#6047
This adds a new wrapping mode called `char-wrap`, which allows for wrapping at any character.
Currently, it only supports the Qt backend, with the other backends falling back to `word-wrap` when this option is selected.
