title: Geometry shader, MaxVertexCount cannot be known
body: <p>I am currently working on a shader where the amount of vertices are not defined by the amount of triangles, my shader puts a cuber every X units.</p>
  
  <p>This means that I cannot know in advance how many cubes it will create and I do not know many vertices it will take.</p>
  
  <p>However you have to put a <code>maxvertexcount[x]</code>. What do I put in the <code>x</code>?</p>
  
  <p>How do I work around this?</p>
  
  <p>Note: I am a beginner at geometry shaders and know next to nothing about them.</p>
