Hi Guy and J.P,
Still struggling to keep up, partly cause I'm a bit cold on the
subject, and partly because I've gone done with a rather pesky cold...

The BufferComponent's in the AttachmentMap area meant to be reasonable
unambiguous, COLOR_BUFFER1 upwards all require MRT to be implemented,
they can't be implement in any other way, so I don't think
implementing the backend to use MRT automatically would be
inappropriate or break previous code.
enum BufferComponent
{
DEPTH_BUFFER,
STENCIL_BUFFER,
COLOR_BUFFER,
COLOR_BUFFER0 = COLOR_BUFFER,
COLOR_BUFFER1 = COLOR_BUFFER+1,
COLOR_BUFFER2 = COLOR_BUFFER+2,
COLOR_BUFFER3 = COLOR_BUFFER+3,
COLOR_BUFFER4 = COLOR_BUFFER+4,
COLOR_BUFFER5 = COLOR_BUFFER+5,
COLOR_BUFFER6 = COLOR_BUFFER+6,
COLOR_BUFFER7 = COLOR_BUFFER+7
};

Can we not just do it when COLOR_BUFFER1 upwards are enabled?
