title: OpenGL: can I mix glBindBuffer with glBindBufferARB?
body: <p>Is glBindBuffer equivelent to glBindBufferARB ?</p>
  
  <p>Are the enums (like GL_ARRAY_BUFFER and GL_ARRAY_BUFFER_ARB) equivilent? Can I use non-_ARB enum in glBindBufferARB?</p>
  
  <p>Can I mix + match glBindBuffer() calls with glBindBufferARB()?</p>
  
  <p>ALSO: if a card supports the _ARB extension, does it always support the core GL function - even if its OpenGL version isn't up to date??</p>
