update_combined_image_sampler()

void MayaFlux::Core::VKDescriptorManager::update_combined_image_sampler	(	vk::Device	device,
		vk::DescriptorSet	set,
		uint32_t	binding,
		vk::ImageView	image_view,
		vk::Sampler	sampler,
		vk::ImageLayout	layout = vk::ImageLayout::eShaderReadOnlyOptimal
	)

Update descriptor set with combined image+sampler.

Parameters

device	Logical device
set	Descriptor set to update
binding	Binding index
image_view	Image view to bind
sampler	Sampler to bind
layout	Image layout (typically eShaderReadOnlyOptimal)

This is the standard way to bind textures in graphics shaders.
