Title: Renamed unions to traditional structs to allow for Swift support.

Unfortunately, Swift seems unable to convert `union` types properly. I converted the `AGKQuad` & `AGKLine` properties to a traditional `struct` types to allow for better inter-compatibility. If people want to access the `.v` member variable of the `AGKQuad`, they can add this extension to their Swift code:

```Swift
extension AGKQuad {
var v: [CGPoint] {
get {
return [tl, tr, bl, br]
}
set {
tl = newValue[0]
tr = newValue[1]
br = newValue[2]
bl = newValue[3]
}
}
}
```
