Resize of a window on OSX results in a black screen

[smasher164]

Resizing a pixel app on OSX results in a black screen until the mouse is released. I believe this is because glfw blocks in PollEvents during the resize, so this loop won't clear the background during that period.

for !win.Closed() {
	win.Clear(colornames.Lightgrey)
	win.Update()
}

However, as mentioned in glfw/glfw#408, one can get the desired behavior by rendering in a refresh callback. Is there anyway for pixel to incorporate this behavior?

Hi! Currently, there is no way incorporate this behavior using Pixel. I don't think it ever will. I understand it can be useful, but Pixel's I/O API is not event based and thus this kind of callback falls out of scope.
