Force the InspectorElement to generate specific types of inspectors, instead of going by the normal checks that try to find a custom inspector and if that fails generates a default inspector.
| Normal | This is the default mode. It just means: check for a custom inspector and if none is found generate the default inspector. |
| Default | Force generation of the default inspector, even if a custom inspector exists. |
| Custom | Force generation of the custom inspector. If no custom inspector is found only a label will be generated, saying no inspector was found. |
| IMGUI | Force generation of the custom IMGUI inspector. If no custom IMGUI inspector is found only a label will be generated, saying no IMGUI inspector was found. |
