1077 * which this extension is exclusively focused on(later cards have GL_ARB_fragment_program).
1078 * If the current card has more than 8 fixed function textures in OpenGL's regular fixed
1079 * function pipeline then the ATI_fragment_shader backend imposes a stricter limit. This
1080 * shouldn't be too hard since Nvidia cards have a limit of 4 textures with the default ffp
1081 * pipeline, and almost all games are happy with that. We can however support up to 8
1082 * texture stages because we have a 2nd pass limit of 8 instructions, and per stage we use
1083 * only 1 instruction.
1084 *
1085 * The proper fix for this is not to use GL_ATI_fragment_shader on cards newer than the
1086 * r200 series and use an ARB or GLSL shader instead
