title: glGenTextures - is there a limit to the number of textures?
body: <p>Is there a limit to the number of textures that can be created in OpenGL - that is, with glGenTextures?</p>
  
  <p>I know that there are some limits imposed by GL, eg. the number of textures that can be used in a fragment shader. However, I haven't been able to find any sort of documentation concerning the total number of integer "texture names" that are available to use.</p>
