Hmm, I don't think so. GL_NONE is not a valid (better listed of allowed)
parameters to the glMemoryBarrier API. I wouldn't try this.
sorry, I did not explain this in enough detail. I meant to use GL_NONE
as a special value that guards the call to glMemoryBarrier, i.e.
if(_sfMemoryBarrier.getValue() != GL_NONE)
glMemoryBarrier(_sfMemoryBarrier.getValue());
Please see the attached patch for details.
This also matches what we do for the face culling mode where GL requires
a glEnable(GL_CULL_FACE) call and glCullFace(GL_BACK) call, but there is
only a single field. If it has a value that is valid for glCullFace() we
issue the glEnable and glCullFace calls otherwise we call glDisable (see
PolygonChunk).
Cheers,
Carsten
