   point sprites in opengl 3.2?
  Hi!I'd like to build a particle system in opengl 3.2 using point sprites but I can't figure out how to access the automaticaly generated texture coordinates. gl_MultiTexCoord0 and gl_TexCoord[].st are deprecated. Is there any other way?   
  You can read about it in the specification in section 3.4.1.
