title: android canvas drawText
body: <p>drawText draws a text from the providing point. But I need different behaviour.<br>
  Let's call the point(x,y) as p.<br>
  How drawText works:<br>
  pMYTEXT<br>
  What I need: 
  MYTpEXT<br>
  So I want to draw text exactly centered with this point. Is this possible?</p>
  
  <p>I think to do it I should measure text and offset the point. But how can I measure it? It has not drawn yet.</p>
