title: Position with Lua in Corona SDK confusion
body: <p>I'm using corona simulator. I displayed display.contentWidth and display.contentHeight .The width is 320 and height is 480. I've also made a text saying "Hello", and played with positioning.</p>
  
  <p>I've noticed the x values looked pretty accurate, I would set x value of text to 0 and the center of it would be half covered and half revealed. Same results for x value of 320, but on the other side of the phone simulator.</p>
  
  <p>When I set y value to 0 it sits right under the Carrier and fake signal strength symbol, fully revealed. When I set the y value to 480 the heights max, it would have about an inch gap from the bottom of the phone. -- My thoughts are that it should be half covered vertically both ways :-S</p>
  
  <p>In corona simulator i'm viewing it in Iphone5 , and notice when I change to Iphone it would reveal as I would expect. With Iphone 5, droid, and some other view it would give me these results.</p>
  
  <p><strong>*</strong> My question is would my program look the same on all devices, or is corona simulator accurate displaying what it would look like. If it displays different on variety of devices, Why?</p>
  
  <pre><code>width = display.newText (display.contentWidth .. "px is Width", 200, 200, nil, 30)
  height = display.newText (display.contentHeight .. "px is Height", 150,300, nil, 30)
  
  text = display.newText ("Hello", 0, 480, nil, 30)
  </code></pre>
