OpenGL Per-Prim control of Transparency SuperSampling AA?

Hello, I’m trying to enable and disable transparency antialiasing on a per-prim basis, as appears to be possible in DX using this call:

pd3dDevice->SetRenderState(D3DRS_ADAPTIVETESS_Y,(D3DFORMAT)MAKEFOURCC(‘S’, ‘S’, ‘A’, ‘A’));

The problem is that my RGBA textures are invoking the super-sampling in many cases when I don’t need it causing performance issues, so I’d like to enable it just when necessary.

Anybody have any ideas how to do this in OGL?
