title: Libgdx gl10.glLineWidth()
body: <p>I have this line:
  Gdx.gl10.glLineWidth(width);
  Now, I do intend to draw a pretty thick line, and, unfortunately when I type in small values like 1 or 5 the line is obviously small. But once I surpass soemthing like 10, it no longer gets larger.  I am passing in direct values in these instances, and so, I am under the impression that GL has a limit or something....  Would I be correct?  Here's my code:</p>
  
  <pre><code>Gdx.gl.glClearColor(0,0,0,1);
      Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
  
      batch.setProjectionMatrix(cam.combined);
      batch.begin();
      batch.draw(bg,0,0,WIDTH,HEIGHT);
      for(Spell a : spells){
          a.draw(batch);
      }
      lc.draw(batch);
      batch.end();
      //((ppux+ppuy)/2f)*4
      Gdx.gl10.glLineWidth(50);//average and then say 1/4 a unit)
      renderer.setProjectionMatrix(cam.combined);
      renderer.begin(ShapeType.Line);
      lp.drawLines(renderer);
      renderer.end();
      batch.begin();
      lp.draw(batch);
      batch.end();
  </code></pre>
  
  <p>lp.drawLines(renderer) calls the following(I just call set color, and draw line):</p>
  
  <pre><code>renderer.setColor(1,1,1,1);
      Elem a = elems.get(spellcombo.get(0));
      Vector2 last = new Vector2(a.x(),a.y());
      for(int i = 1; i &lt; spellcombo.size(); i++){
          a = elems.get(spellcombo.get(i));
          Vector2 cur = new Vector2(a.x(),a.y());
          renderer.line(last.x, last.y, cur.x, cur.y);
          last = cur;
      }
      renderer.line(last.x,last.y,mx,my);
      Gdx.gl.glEnable(GL10.GL_BLEND);
      Gdx.gl.glBlendFunc(GL10.GL_SRC_ALPHA, GL10.GL_ONE_MINUS_SRC_ALPHA);
      renderer.setColor(1, 0, 0, .2f);
      for(Elem e : elems){
          int id = elems.indexOf(e);
          if(ComboManager.validSpell(spellcombo,id))
              renderer.line(last.x,last.y,e.x(),e.y());
      }
  </code></pre>

  <p>I don't really know how to fix, and google wasn't particularily helpfull.
  Thanks!</p>
