Description

The following tokens are valid for GL.DrawBuffer:

NONE, GL_FRONT_LEFT, GL_FRONT_RIGHT, GL_BACK_LEFT, GL_BACK_RIGHT, GL_FRONT, GL_BACK, GL_LEFT, GL_RIGHT, GL_FRONT_AND_BACK, and GL_AUXi

GL.DrawBuffers may accept the following tokens:

         NONE
        DRAW_BUFFER0                        0x8825
        DRAW_BUFFER1                        0x8826
        DRAW_BUFFER2                        0x8827
        DRAW_BUFFER3                        0x8828
        DRAW_BUFFER4                        0x8829
        DRAW_BUFFER5                        0x882A
        DRAW_BUFFER6                        0x882B
        DRAW_BUFFER7                        0x882C
        DRAW_BUFFER8                        0x882D
        DRAW_BUFFER9                        0x882E
        DRAW_BUFFER10                       0x882F
        DRAW_BUFFER11                       0x8830
        DRAW_BUFFER12                       0x8831
        DRAW_BUFFER13                       0x8832
        DRAW_BUFFER14                       0x8833
        DRAW_BUFFER15                       0x8834

Right now, both functions are defined to take the same tokens, even though these result in an InvalidOperation. Solution: move second list into a new enum and modify DrawBuffers to use it.

The correct tokens are COLOR_ATTACHMENT[i]n[/i], not DRAW_BUFFER[i]n[/i].

Fixed in revision 1805 using tables 4.4 - 4.6, pg. 184 of the 3.1 specs.
