Camera Constructor adaption for doing what GameMaker should've had been doing along time ago...

Lens v1.1.1

Camera Constructor wrapper for GameMaker Studio 2.3.2+.

This is just a drop in for most of the camera_* functions presented in GameMaker Studio 2 as methods via a constructor, as .PascalCase().
It also outright removes having to supply a cameraID for every method. Leaving it down to just providing the arguments.
Most of the methods are chainable as well.

Use case:

// Creates a new Lens instance. Each instance carries its own cameraID.
cam = new Lens();
cam.SetViewCam(0).SetViewPos(32,32).SetViewSize(1280,720).Apply();

Methods

While most of it is pretty much plug in play (without having to supply CameraID), there's a few extra methods included.

.GetViewSpeed()

Returns: an array that contains the results from .GetViewSpeedX() and .GetViewSpeedY()

.GetCameraID()

Returns: CameraID

.SetViewCamera(view_camera)

Basically the same as view_camera[view_num] = camID. but internally tracks the cameraID for when .free() is called.

.Free()

Frees the internal cameraID.

.GetCameraRect()

Returns an array with ViewX, ViewY, ViewX + ViewW, ViewY + ViewH.
