render port is being replaced with xorg-renderproto port

[Ryan Schmidt]

This message is relevant to anyone using ports that until now  
depended on the render port:

* cairo / cairo-devel
* gthumb
* gtk2
* libgdiplus
* rxvt-unicode
* wine / wine-devel
* xrender

The render port has been replaced with the xorg-renderproto port.  
They are the same software; the latter is just a newer version. So we  
are removing the render port.

If you use any of the above ports, you may find at your next update  
that MacPorts wants to install xorg-renderproto but that it conflicts  
with the render port:

Error: Target org.macports.activate returned: Image error: /opt/local/ 
include/X11/extensions/render.h is being used by the active render  
port.  Please deactivate this port first, or use the -f flag to force  
the activation.

What you should do if you get this message is forcibly uninstall the  
render port and then activate the xorg-renderproto port.

sudo port -f uninstall render
sudo port activate xorg-renderproto

Sorry for the inconvenience!
