getMemoryRequirementsForBuffer/Image functions

[Crisspl]

Description

I find them useful, can we have this?

[devshgraphicsprogrammingjenkins]

[CI]: Can one of the admins verify this patch?

[devshgraphicsprogramming]

But we already have them, here:

Nabla/include/nbl/video/IDeviceMemoryBacked.h

Line 74 in 8e95b81

inline const SDeviceMemoryRequirements& getMemoryReqs() const {return m_cachedMemoryReqs;}

Both IGPUImage and IGPUBuffer inherit from IDeviceMemoryBacked.

The constructor of IGPUBuffer and IGPUImage are fed with already created VkHandles and the constructor of the base class fills out everything for you.

Nabla/src/nbl/video/CVulkanDeviceMemoryBacked.cpp

Line 21 in 8e95b81

vk.vkGetBufferMemoryRequirements2(device->getInternalObject(),&vk_memoryRequirementsInfo,&vk_memoryRequirements);
