title: Opengl TRIANGLE_STRIPS creating duplicate ghost
body: <p>I had some fun making my first shaders and my first test subject was a 100x100 quad faced picture. 
  I thought I would learn how to use <code>TRIANGLE_STRIP</code> so I switched it, moved one of the vertex calls so it would look square again. Turned my shader on and there was a duplicate right behind it of only one face but it had the entire texture on it. I have only one set of draw calls for this shape....</p>
  
  <p>Heres my shape code:</p>
  
  <pre><code>glBegin(GL_TRIANGLE_STRIP);
      float vx;
      float vy;
      for(float x=0; x&lt;100; x++){
          for(float y=0; y&lt;100; y++){
              float vx=x/5.0;
              float vy=y/5.0;
              glTexCoord2f(0.01*x, 0.01*y);
              glVertex3f(vx, vy, 0);
  
              glTexCoord2f(0.01+0.01*x, 0.01*y);
              glVertex3f(.2+vx, vy, 0);
  
              glTexCoord2f(0.01*x, 0.01+0.01*y);
              glVertex3f(vx, .2+vy, 0);
  
              glTexCoord2f(0.01+0.01*x, 0.01+0.01*y);
              glVertex3f(.2+vx, .2+vy, 0);
      }}
  glEnd();
  </code></pre>
  
  <p>And my (vertex) shader code:</p>
  
  <pre><code>uniform float uTime,uWaveintensity,uWavespeed;
  uniform float uZwave1,uZwave2,uXwave,uYwave;
  void main(){
  vec4 position = gl_Vertex;
  gl_TexCoord[0] = gl_MultiTexCoord0;
  position.z=((sin(position.x+uTime*uWavespeed)*uZwave1)+(sin(position.y+uTime*uWavespeed))*uZwave2)*uWaveintensity;
  position.x=position.x+(sin(position.x+uTime*uWavespeed)*uXwave)*uWaveintensity;
  position.y=position.y+(sin(position.y+uTime*uWavespeed)*uYwave)*uWaveintensity;
  gl_Position = gl_ModelViewProjectionMatrix * position;
  }
  </code></pre>
  
  <p>If anyone has any info on drawing more efficiently with shared vertices(triangle_strips) I've googled but I don't understand any so far XD. I wanna know.</p>

  <p>same thing same angle,lines=ghost</p>

  <p>I see whats happening now, but I don't know how to fix it.</p>
