glColorTableExt against glPixelTransferi


We succeeded in using color palettes on textures with glPixelTransferf and glColorTableExt. glColorTableExt requires an extension called: GL_EXT_paletted_texture. glPixelTransferf is built in opengl 1.1.

Can you tell if glColorTableExt has better performance ?
What do we need the extension if the same thing can be done with glPixelTransferi ?
