Dear Mesa team,

First thank you for your work on Mesa and it's open sourcing.

I am looking for the GL_PERSPECTIVE_CORRECTION_HINT implementation details.

If I am correct, as of openGL 2.1, this hint is of no more use as all interpolations (color, texture coordinates, glsl varying vertex attributes) are in a perspectivly correct form.

I grep'ed "GL_PERSPECTIVE_CORRECTION_HINT" on the 6.3.2 and 6.5.2 source trees, and followed the thread but was unable to conclude.

So am I asking if would point to me the relevant file/functions to search for this interpolant.

Anyway, thank you again for Mesa,
Pierre Boulenguez
