mesa: fix error handling for glMaterial*
Trigger GL_INVALID_ENUM error if the face paramter is not a valid value. Trigger GL_INVALID_VALUE error if the GL_SHININESS value is out side [0, ctx->Constant.MaxShiniess]. v2: fix the max shininess value. v3: suggested by Brian, move the face check into glMaterialfv function to reduce code duplicate. Also, refactor the error message. Signed-off-by: Yuanhan Liu <[email protected]> Signed-off-by: Brian Paul <[email protected]>
