2        ATI fragment shader Extension program file.
3        setup by NFZ
4        extracted from ATI 8500 SDK

6** GL_ATI_fragment_shader
7**
8** Support:
9**   Rage 128 * based  : Not Supported
10**   Radeon   * based  : Not Supported
11**   R200     * based  : Supported
12**   R200 : 8500, 9000, 9100, 9200
13**   also works on R300 but pointless since ARBFP1.0 supported
