Comments7
Deletes all or part of the vector image.
Note: When you delete a certain object, it may or may not effect other unselected objects sharing vertices with the selected object. This depends on the current bind vertices mode set by LVectorBase::SetBindVerticesMode.
Note: In DirectX, you cannot delete objects, therefore this function does nothing.
