From 4bdf8547f4dc1a383bf4e67110f44610a3790189 Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Thu, 16 Jan 2020 14:39:58 -0600 Subject: [PATCH] vulkan/wsi: Implement VK_KHR_swapchain_mutable_format This is only the core WSI code for the extension. It adds the image format list and the flags to vkCreateImage as well as handling things properly in the modifier queries.
