`-nocursor`. The RFB client asks for Raw and CopyRect and nothing else, so
x11vnc has no cursor pseudo-encoding to send a shape through and composites
the pointer into the framebuffer instead. That is a second cursor in the
picture, a round trip behind the real one, and on a bare X server with no
window manager it is the big black X of the root cursor rather than an arrow.
Verified on the live socket by parking the pointer at 100,100 and counting
what is not stage-teal in a 48x48 patch around it: 960 pixels before, 0 after.
Not fixed by teaching the client the cursor encodings — the answer is not to
draw the remote cursor better, it is not to draw it at all.
