determineColorSpace()

static vr::EColorSpace xrt::state_trackers::openvr::determineColorSpace ( VkFormat  format )

static

When dealing with an Auto colour space, pick the correct one to use based on the format.

According to the OpenVR documentation, all 8-bit per component formats are sRGB/Gamma

resolveSwapchainStorageFormat()

static VkFormat xrt::state_trackers::openvr::resolveSwapchainStorageFormat ( VkFormat  source_format, VkFormat  sample_format  )

static

Given the format that the compositor will later sample with, return the storage-compatible format to write into.
