Subject: vulkan/wsi: Filter modifiers with ImageFormatProperties
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a218f132786118c6e0be64d5b85fe9a5c18c634d;p=mesa.git

vulkan/wsi: Filter modifiers with ImageFormatProperties

Just because a modifier is returned for the given format, that doesn't
mean it works with all usages and flags.  We need to filter the list by
calling vkGetPhysicalDeviceImageFormatProperties2.
