JIRA: https://jira.appcelerator.org/browse/TIMOB-25684

Adds homescreen like parallax effect to views based on Marcel Pociot's module https://github.com/mpociot/TiMotionEffects

The unit-tests are missing which will prevent our Danger.js checks from passing. I prepared them for you, please create a file ti.ui.view.addontest.is in tests/:

describe('Titanium.UI.View', function() {

  it.ios('.horizontalMotionEffect, .verticalMotionEffect', function(finish) {
    var win = Ti.UI.createWindow({
      backgroundColor: 'blue'
    });

    var view = Ti.UI.createView({
      horizontalMotionEffect: {
        min: -50,
        max: 50
      },
      verticalMotionEffect: {
        min: -50,
        max: 50
      }
    });

    win.addEventListener('open', function() {
        // horizontalMotionEffect
        should(view.horizontalMotionEffect).be.an.Object;
        should(view.horizontalMotionEffect.min).be.a.Number;
        should(view.horizontalMotionEffect.max).be.a.Number;

        // verticalMotionEffect
        should(view.verticalMotionEffect).be.an.Object;
        should(view.verticalMotionEffect.min).be.a.Number;
        should(view.verticalMotionEffect.max).be.a.Number;

        finish();
    });

    win.add(view);
    win.open();
  });
});

Also, please adjust the docs in apidoc/Titanium/UI/View.yml to include the properties, with a since version of 7.1.0.

EDIT: @chmiiller I've update the test-case to actually call finish(). Otherwise the test will time-out. Also, the test is brain-written, so you may need to tweak some details to pass.

Thanks @hansemannn ! I've just updated tests and added the properties into View's documentation. Is it missing something else?

Test suite crashed on iOS simulator. Please see the crash log for more details. I can't access the crash logs =/
