-- = Description
--
-- If no resolve mode is otherwise specified, 'RESOLVE_MODE_AVERAGE_BIT' is
-- used.
--
-- Note
--
-- No range compression or Y′CBCR model conversion is performed by
-- 'RESOLVE_MODE_EXTERNAL_FORMAT_DOWNSAMPLE_ANDROID'; applications have to
-- do these conversions themselves. Value outputs are expected to match
-- those that would be read through a
-- <https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#textures-sampler-YCbCr-conversion-modelconversion Y′CBCR sampler using >.
-- The color space that the values should be in is defined by the platform
-- and is not exposed via Vulkan.

-- | 'RESOLVE_MODE_EXTERNAL_FORMAT_DOWNSAMPLE_ANDROID' indicates that rather

-- downsampled into a Y′CBCR format image specified by an external Android
-- format. Unlike other resolve modes, implementations can resolve multiple
-- times during rendering, or even bypass writing to the color attachment
-- altogether, as long as the final value is resolved to the resolve
-- attachment. Values in the G, B, and R channels of the color attachment
-- will be written to the Y, CB, and CR channels of the external format
-- image, respectively. Chroma values are calculated as if sampling with a
-- linear filter from the color attachment at full rate, at the location
-- the chroma values sit according to
-- 'Vulkan.Extensions.VK_ANDROID_external_format_resolve.PhysicalDeviceExternalFormatResolvePropertiesANDROID'::@chromaOffsetX@,
-- 'Vulkan.Extensions.VK_ANDROID_external_format_resolve.PhysicalDeviceExternalFormatResolvePropertiesANDROID'::@chromaOffsetY@,
-- and the chroma sample rate of the resolved image.
