* Fixed various queryInterface implementations (#6863)AlexisPollonni2025-04-23
| | | | | | | | | | | * Fix: Improper implementation in RendererBase::queryInterface In the case an arbitrary uuid was passed to RendererBase::QueryInterface it would return SLANG_OK while the outObject is null. This is improper and unexpected from an IUnkown implementation. Additionally, the function did not call addRef() when concerning an IDevice interface. * Fix: DebugTransientResourceHeap::queryInterface returns wrong interface When trying to query for the transient heap if the debug layer is enabled, queryInterface would set the outObject to the inner api specific heap (ex: vk::TransientResourceImpl) and NOT the debug heap. This causes a side effect when creating a command buffer that debug wrappers would not be used. The debug version will not be returned, and this snowballs causing an access violation when trying to bind a compute pipeline state. After this fix, debug wrappers for transient heaps, command buffers, encoders, etc... wil be used correctly. * fix weird whitespace change
