xorg-*proto ports and system_x11

[Marcus Calhoun-Lopez]

Why do the xorg-* ports which have a system_x11 variant still
pull in xorg-*proto ports?
If I need to install install Xft2 +system_x11 (for tk),
I still get header files from xorg-xproto.

I am far from an expert on X11, but it seems to me that we either need to
add a system_x11 variant to the proto ports or trim down the dependencies
of the current system_x11 ports.

I know that there has been much discussion about X11 recently
(some of which I have missed).
Please forgive me if this was covered already.
