Description
This extension enables an application to import QNX Screen
_screen_buffer objects created outside of the Vulkan device into Vulkan
memory objects, where they can be bound to images and buffers.
Some _screen_buffer images have implementation-defined external
formats that may not correspond to Vulkan formats.
Sampler Y′CBCR conversion can be used to sample from these images and
convert them to a known color space.
_screen_buffer is strongly typed, so naming the handle type is
redundant.
The internal layout and therefore size of a _screen_buffer image may
depend on native usage flags that do not have corresponding Vulkan
counterparts.
