title: font.setColor method not working after libGDX update to latest version
body: <p>I have some 3-4 years old game project in libGDX. Now I decided to update it and to move from Eclipse to Android studio. So, I installed A.S. downloaded and installed fresh libGDX project. Then added my old source files and assets. All went well, with some minor changes game runs. Except font.setColor is not working any more - text on screen is black. Transparency is not working neither. That worked well before.</p>
  
  <p>So, my font is generated with Hiero, and it's white (I saw that in some other questions here that it must be white).</p>
  
  <pre><code>font = new BitmapFont(Gdx.files.internal("fonts/bundy.fnt"),
                  Gdx.files.internal("fonts/bundy_0.png"), false);
  ...
  
  font.setColor(0.2f, 0.5f, 0.2f, 1.0f);
  font.draw(game.batch, "MAP" , 835,580);
  </code></pre>
  
  <p>To mention that I used </p>
  
  <pre><code>import com.badlogic.gdx.graphics.GL10;
  </code></pre>
  
  <p>but now I moved to</p>
  
  <pre><code>import com.badlogic.gdx.graphics.GL20;
  </code></pre>
  
  <p>since GL10 is not supported any more.</p>
  
  <p>Also, now I'm using <code>GlyphLayout</code> class to get text boundaries. I don't see any other change that could have any influence to font color.</p>
  
  <p>Any idea why setColor is not working? Is there some new step added  meanwhile that I have to do?</p>
