new getCamera function for V1 & V2

Increasing access

It would provide compatability between versions 1 & 2 but more importantly provide users and library creators a standard method to access, modify and set cameras.

Most appropriate sub-area of p5.js?

• Accessibility
• Color
• Core/Environment/Rendering
• Data
• DOM
• Events
• Image
• IO
• Math
• Typography
• Utilities
• WebGL
• Build process
• Unit testing
• Internationalization
• Friendly errors
• Other (specify if possible)

Feature request details

I suggest a new function for both V1 and V2 that returns a reference to the current camera object, something like

// V2
RendererGL.prototype.getCamera = function(cam) {
    return this.states.setValue('curCamera', cam);
}

// V1
RendererGL.prototype.getCamera = function(cam) {
    return this._curCamera;
}

This would provide compatibility between versions.

Additional comment:

I see that in version 2.0.5 the createCamera method still sets the newly created camera as the default. See issues
5941, 7077 and 7102
