It just places the cursor in the middle of the screen. The reason it
uses ->xvirtres and ->yvirtres instead of ->xres and ->yres is because
the axes may be reversed if the screen is in portrait mode.

The Gr*() functions in client.c are just stubs which generate some
network protocol that causes the corresponding Gr*Wrapper() function in
srvnet.c to be called, which in turn decodes the parameters and calls
the actual function in the server, usually located in srvfunc.c. When in
"client linked into server" mode, client.c and srvnet.c are not linked
in and the client calls the functions in srvfunc.c directly.

If it doesn't work, you're not hitting it with a big enough hammer
