Detailed Description

A decoded floating-point image, always four channels.

Four rather than three because Vulkan has no widely-supported three-channel float format - R32G32B32Sfloat is optional and absent on plenty of desktop parts, while R32G32B32A32Sfloat is universal. The alpha is padding and always 1
