+ * Returns a property group containing read-only debug information associated
+ * with this GPU context. All properties are optionally provided and may differ
+ * between GPU backends and SDL versions.
+ *
+ * The following properties are provided by SDL:
+ *
+ * ### `SDL_PROP_GPU_DEVICE_DEBUG_NAME_STRING`
+ *
+ * Contains the name of the underlying device as reported by the system driver.
+ * This string has no standardized format, is highly inconsistent between
+ * hardware devices and drivers, and is able to change at any time. Do not
+ * attempt to parse this string as it is bound to fail at some point in the
+ * future when system drivers are updated, new hardware devices are introduced,
+ * or when SDL adds new GPU backends or modifies existing ones.
+ *
+ * Strings that have been found in the wild include:
+ *
+ * - GTX 970
+ * - GeForce GTX 970
+ * - NVIDIA GeForce GTX 970
+ * - Microsoft Direct3D12 (NVIDIA GeForce GTX 970)
+ * - NVIDIA Graphics Device
+ * - GeForce GPU
+ * - P106-100
+ * - AMD 15D8:C9
+ * - AMD Custom GPU 0405
+ * - AMD Radeon (TM) Graphics
+ * - ASUS Radeon RX 470 Series
+ * - Intel(R) Arc(tm) A380 Graphics (DG2)
+ * - Virtio-GPU Venus (NVIDIA TITAN V)
+ * - SwiftShader Device (LLVM 16.0.0)
+ * - llvmpipe (LLVM 15.0.4, 256 bits)
+ * - Microsoft Basic Render Driver
+ * - unknown device
+ *
+ * The above list shows that the same device can have different formats, the
+ * vendor name may or may not appear in the string, the included vendor name may
+ * not be the vendor of the chipset on the device, some manufacturers include
+ * pseudo-legal marks while others don't, some devices may not use a marketing
+ * name in the string, the device string may be wrapped by the name of a
+ * translation interface, the device may be emulated in software, or the string
+ * may contain generic text that does not identify the device at all.
+ *
+ * ### `SDL_PROP_GPU_DEVICE_DEBUG_DRIVER_NAME_STRING`
+ *
+ * Contains the self-reported name of the underlying system driver.
+ *
+ * Strings that have been found in the wild include:
+ *
+ * - Intel Corporation
+ * - Intel open-source Mesa driver
+ * - Qualcomm Technologies Inc. Adreno Vulkan Driver
+ * - MoltenVK
+ * - Mali-G715
+ * - venus
+ *
+ * ### `SDL_PROP_GPU_DEVICE_DEBUG_DRIVER_VERSION_STRING`
+ *
+ * Contains the self-reported version of the underlying system driver. This is a
+ * relatively short version string in an unspecified format. If
+ * SDL_PROP_GPU_DEVICE_DEBUG_DRIVER_INFO_STRING is available then that property
+ * should be preferred over this one as it may contain additional information
+ * that is useful for identifying the exact driver version used.
+ *
+ * Strings that have been found in the wild include:
+ *
+ * - 53.0.0
+ * - 0.405.2463
+ * - 32.0.15.6614
+ *
+ * ### `SDL_PROP_GPU_DEVICE_DEBUG_DRIVER_INFO_STRING`
+ *
+ * Contains the detailed version information of the underlying system driver as
+ * reported by the driver. This is an arbitrary string with no standardized
+ * format and it may contain newlines. This property should be preferred over
+ * SDL_PROP_GPU_DEVICE_DEBUG_DRIVER_VERSION_STRING if it is available as it
+ * usually contains the same information but in a format that is easier to read.
+ *
+ * Strings that have been found in the wild include:
+ *
+ * - 101.6559
+ * - 1.2.11
+ * - Mesa 21.2.2 (LLVM 12.0.1)
+ * - Mesa 22.2.0-devel (git-f226222 2022-04-14 impish-oibaf-ppa)
+ * - v1.r53p0-00eac0.824c4f31403fb1fbf8ee1042422c2129
+ *
+ * As well as the multiline string (which has a trailing newline):
+ *
+ * ```
+ * Driver Build: 85da404, I46ff5fc46f, 1606794520
+ * Date: 11/30/20
+ * Compiler Version: EV031.31.04.01
+ * Driver Branch: promo490_3_Google
+ * ```
+ *
+ * ### `SDL_PROP_GPU_DEVICE_DEBUG_VULKAN_CONFORMANCE_STRING`
+ *
+ * When using the Vulkan backend, contains the highest Vulkan version number
+ * that the system driver claims that the underlying hardware conforms to. This
+ * is self-reported and may not be truthful.
+ *
+ * Strings that have been found in the wild include:
+ *
+ * - 0.0.0.0
+ * - 1.0.0.0
+ * - 1.3.8.2
+ *
+ * \param device a GPU context to query.
+ * \returns a valid property ID or 0. A value of 0 indicates that no properties
+ *          are available and is not an error. The returned property group is
+ *          owned by SDL and has the same lifetime as the containing context. It
+ *          should not be destroyed manually when no longer needed.
+ *
+ * \since This function is available since SDL 3.4.0.
