Hi Ian,

It was Adobe Photoshop CS4. 

It actually searches for both GL_ARB_texture_cube_map and
GL_EXT_texture_cube_map, but somewhere along the way it ignores the
former and outputs in a system information log:

  Cube Maps NOT SUPPORTED...

It is quite possible that it is a bug in the system information output
code, and the GL code actually uses cubemaps. But it is almost
impossible to be sure, as Photoshop is very complex and has several
distinct uses of OpenGL (e.g., effects, visualization, etc). And at any
rate if an user would see the above message it would get legitimately
worried.

It seemed simpler just to list GL_EXT_texture_cube_map!

I don't have my NVIDIA machine handy, but I checked it before committing
this and IIRC they indeed had this extension listed.
