Draw an image into a widget. Requires a call to app::set_visual(Mode::Rgb8).unwrap(). A negative depth flips the image horizontally, while a negative line data flips it vertically. Allows passing a line-data parameter

Errors

Errors on invalid or unsupported image formats

Safety

Passing wrong line data can read to over or underflow
