title: Is it possible to set dynamic frame-rate with cocos2d-x?
body: <p>I want to write a text reader which has special effects with cocos2d-x, so the most time the graph will be static. If I use cocos2d-x, it's just heavily consuming battery power.</p>
  
  <p>So is it possible to adjust cocos2d-x's frame rate by coding? And how? I want to reduce frame rate when text's static, and increase frame rate when paging up or down.</p>
  
  <p>Or any good idea for this goal on Android? (Page turning animations and more efficient text rendering.)</p>
