[Piglit] glSecondaryColorPointer with size 4

[Vinson Lee]

Is 4 a valid size parameter for glSecondaryColorPointer?

The piglit tests bgra-sec-color-pointer and glsl-routing call glSecondaryColorPointer with a size parameter of 4. Both these tests also crash on Mac OS X when glDrawArrays is called after glSecondaryColorPointer.

The following is from the OpenGL documentation.

glSecondaryColorPointer(size, type, stride, pointer)
size - Specifies the number of components per color. Must be 3.
GL_INVALID_VALUE is generated if size is not 3.


EXT_vertex_array_bgra specification
    5.  So should 4 be allowed as a valid size parameter for
        glSecondaryColorPointer?

        RESOLVED:  Not for this extension.  We leave it to another
        extension or core revision could extend the secondary color to
        4 components.
