class ImportedImages
Defined at line 67 of file ../../src/graphics/display/drivers/virtio-gpu-display/imported-images.h
Manages a display engine's collection of imported images.
Instances are not thread-safe, and must be used on a single thread or
synchronized dispatcher.

Upon success, `FindSysmemInfoById()` will return the image buffer
information retrieved from sysmem, and `FindImageById()` will return an
empty instance. The driver code calling this method should check that the
sysmem buffer and image constraints are acceptable, and should then
populate the `ImportedImage` instance with valid data.

ImportedBufferCollection * FindBufferCollectionById (display::DriverBufferCollectionId buffer_collection_id)Returns null if no collection with the given ID exists.
The returned pointer is valid until the collection is mutated by calling an
Import*() or Release*() method.
