fixed_width

When fixed_width is applied to the DCL dialog root item (the "dialog" entry) and set to false, the entire DCL dialog becomes resizable.

For a resizable DCL dialog, all tiles are automatically scaled resp. positioned to provide a smooth and visually correct appearance.

This is a BricsCAD only feature, but it won't disturb usage of the DCL dialog in other CAD applications.
By design of DCL, it is permitted to add any custom attribute; custom attributes simply have no effect, apart from the possibility to fetch them using the get_attr function.

special behaviour applies : when fixed_width is applied to the dialog root
