Occasional TypeError upon pressing the 1:1 button

[Technologicat]

It sometimes happens that w and/or h are of type str, not int. Then trying to compute (w + h) / 2 raises a TypeError, and the image dimensions are not updated.

Unfortunately this only happens sometimes, and I haven't yet figured out exactly when. The last time this hit me, I was in the img2img tab.

What I do know, however, is that this can be fixed by introducing an explicit typecast, like this:

def avg_from_dims(w, h):
    w = int(w)
    h = int(h)
    avg = (w + h) // 2
    if (w + h) % 2 != 0:
        avg += 1
    return avg
