Doesn't record MapBox

[kushsolitary]

Hi,

I am trying to create a recording with an animated map (powered by Mapbox, runs on Metal) in the background but the map isn't rendered at all.

What I am trying to render:

What FlipBook renders:

Is this is a known limitation or a bug?

Changing the fb_makeViewSnapshot function to this fixed it:

func fb_makeViewSnapshot() -> Image? {
    UIGraphicsBeginImageContextWithOptions(bounds.size, true, 0)
    
    drawHierarchy(in: bounds, afterScreenUpdates: false)
    let rasterizedView = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()
    return rasterizedView
}

Here is the explanation: mapbox/mapbox-gl-native#6070 (comment)

@chatwyn An MGLMapView isn't a normal layer-backed view, but rather based on GLKView for OpenGL rendering. See mapbox/mapbox-gl-native#1701 for more background, but you can probably use a combo of -[GLKView snapshot] and your current approach for the parts atop the GL view for now.

I also faced a crash when I was rendering a MKMapView.

Opened a PR for it.
