selectSurfaceFormat()

bool selectSurfaceFormat ( const VkPhysicalDevice physical_device, const VkSurfaceKHR surface, bool use_hdr_swapchain, VkSurfaceFormatKHR & r_surfaceFormat )

static

Select the surface format that we will use.

We will select any 8bit UNORM surface.

LOG

CLG_LogRef LOG = {"ghost.context"}

vulkan_instance

std::optional<GHOST_InstanceVK> vulkan_instance

static

A shared device between multiple contexts.

The logical device needs to be shared as multiple contexts can be created and the logical vulkan device they share should be the same otherwise memory operations might be done on the incorrect device.
