When selecting a memory type, there are some property flags we need (e.g., VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT, without which we cannot vkMapMemory), and others we'd simply prefer (e.g., VK_MEMORY_PROPERTY_DEVICE_LOCAL_BIT, which may have a performance impact, but otherwise shouldn't be required). By specifying these separately, we can fall back to a memory type which doesn't have everything we want, but which should still work, rather than giving up.

Simple DirectMedia Layer (SDL) Version 3.0
Simple DirectMedia Layer is a cross-platform development library designed to provide low level access to audio, keyboard, mouse, joystick, and graphics hardware via OpenGL and Direct3D. It is used by video playback software, emulators, and popular games including Valve's award winning catalog and many Humble Bundle games.
More extensive documentation is available in the docs directory, starting with README.md. If you are migrating to SDL 3.0 from SDL 2.0, the changes are extensively documented in README-migration.md.
Enjoy!
