Function xray::screenshot_test

pub fn screenshot_test<S: ScreenshotIo, C: ScreenshotCaptor>(
    screenshot_io: S, 
    screenshot_captor: C, 
    x: i32, 
    y: i32, 
    width: u32, 
    height: u32
) -> Result<(), XrayError>

Tests the rendered image against the screenshot and returns a Ok(()) if they match, and a Err(ScreenshotError) should the comparison not match or encounter an error.

The reference image is loaded using screenshot_io.load_reference(), while the test image is captured using screenshot_captor.capture_image(x, y, width, height).
