Struct ImageRef 

pub struct ImageRef<'a> {
    pub id: u64,
    pub version: u64,
    pub view: PixelView<'a>,
}

An image with the identity a painter needs to cache it.

The same shape as AtlasPage, for the same reason: the software rasteriser composites the pixels and is done, and a GPU would rather upload them once and draw a quad forever. id says which image and version whether its bytes are the ones uploaded last time — it changes when the pixels are replaced and never otherwise.

Fields

id: u64

Unique per image for the life of the process.

version: u64

Changes whenever the pixels do.

view: PixelView<'a>

The pixels, premultiplied.
