- Use native texture swizzling when available.
- Set default value of the `MVK_ALLOW_METAL_FENCES` environment variable to `1 (true)`,
to enable use of `MTLFence` for Vulkan semaphores, by default.
- Support additional capabilities in 1D images, including rendering, clearing,
and mipmaps. Add `MVK_CONFIG_TEXTURE_1D_AS_2D` environment variable to
enable/disable these capabilities.
- Use placement `MTLHeaps` for `VkDeviceMemory` when possible.
- Report heap sizes accurately when possible.
- Add support for additional colorspace options.
