GL_TEXTURE_RECTANGLE_ARB and glTexGen()

OpenGL OpenGL: Basic Coding

Pretty simple question here I think…

When using GL_TEXTURE_RECTANGLE_ARB and glTexGen() do I need to compensate for GL_TEXTURE_RECTANGLE_ARB not using 0…1 coordinates by scaling the texture matrix or will glTexGen() handle it for me?

I checked the ARB_texture_rectangle extension but it did not mention glTexGen().

No, the whole point is 0-1 maps to the rectangle on each axis.
