VkRectLayerKHR

The VkRectLayerKHR structure is defined as:

typedef struct VkRectLayerKHR {
    VkOffset2D offset;
    VkExtent2D extent;
    uint32_t layer;
} VkRectLayerKHR;

• offset is the origin of the rectangle, in pixels.
• extent is the size of the rectangle, in pixels.
• layer is the layer of the image. For images with only one layer, the value of layer must be 0.

Some platforms allow the size of a surface to change, and then scale the pixels of the image to fit the surface. VkRectLayerKHR specifies pixels of the swapchain’s image(s), which will be constant for the life of the swapchain.
