DCAF require VISUALIZATION for correct work.
In some scenario DRAWEXE can generate a dublicates of the
internal static singletons. This means each dynamic library
will have their own instance of the static singleton.
Update all direct library loading to use the DCAF plugin
mechanism. This will ensure that the DCAF plugin is loaded
only once and that the correct instance is used.
Originally issue is reproduced only Linux with dlopen with "RTLD_LAZY".
Can be resolved additionally adding "RTLD_LAZY | RTLD_GLOBAL" for dlopen
# Add test to verify import
* Note: Each layer contains a valid name, but only one contains a link to the shape, so .step file contains only one valid Layer.
