extension MTLRegion has wrong (+1) maxX maxY maxZ

[atrbx5]

if my texture has size of 5
then my minX is 0
and my maxX is 4
with current implementation it's 5

public extension MTLRegion {
    var maxX: Int {
        return self.origin.x + self.size.width
    }    
    var maxY: Int {
        return self.origin.y + self.size.height
    }    
    var maxZ: Int {
        return self.origin.z + self.size.depth
    }
