Describe the pull request
Currently, if a class holds an interface pointer or reference to any object, it cannot use it to call contra-variant methods in sub-classes. For example, a
ICommandBufferpointer cannot be submitted to aVulkanCommandQueue, even if the instance actually is aVulkanCommandBufferand theICommandQueueinterface exposes a proper overload, that performs a dynamic up-cast. This PR addresses this issue by importing contra-variant overloads into sub-classes, which removes the manual casting involved.
