Appium 1.8.0: moveTo Absolute to Relative Coordinates Change

gistfile1.txt

* Appium 1.8.0 introduced a change to the way the `moveTo` touch events works
* Previously, `moveTo` treats coordinates as relative, now `moveTo` accepts coordinates 
  (in compliance with the spec)


Example
========================
* Python sample

```python
driver
  .press(x1, y1)
  .wait()
  .move_to(x2, y2)
  .release()
```

* Pre Appium 1.8.0
  * The `touch` action would press down at absolute coordinates x1, x2
  * The `move_to` action moves to the x2, y2 relative to x1, y1 (in absolute terms, it moves to x1 + x2, y1 + y2)
* Appium 1.8.0 and onwards
  * The `touch` action would press down at absolute coordinates x1, x2 (same as before)
  * The `move_to` action moves to the absolute x2, y2 coordinate
  
  
Adapting to Changes
=======================
* If this change broke one of your `moveTo` scripts, the way to fix it is to simply add x1 and y1 to your relative coordinates
* So if your code looked like this before:

```python
driver
  .press(x1, y1)
  .wait()
  .move_to(x2, y2)
  .release()
```

* It needs to look like this now:

```python
driver
  .press(x1, y1)
  .wait()
  .move_to(x1 + x2, y1 + y2)
  .release()
```
