OpenGL and ICM Color Management

I'm looking into ways to move my plugins to the use of OpenCL and OpenGL to take advantage of the power in modern GPUs.

Specifically, with the Windows GDI, ICM color management can be set up to be done automatically through calls like BitBlt(), and in fact I do this.

Can someone here point me in the right direction to learn how one might best handle color spaces when using OpenGL in place of the older Windows GDI calls?

Thanks!
