When distorting the current picture, when texture (i.e. source)
coordinates go off-screen, two things can happen:
1) the coordinates wrap around (i.e. the texture repeats)
2) the coordinates are clamped
Right now, you are seeing behaviour #1. You can go to #2 with this line:
bTexWrap=0
(it also works in per-frame equations, if you want to play with it)
You can also add a border in combination with bTexWrap=0, to make those
area black. Try this:
ob_a=1
ob_size=0.01
(There are also ob_[r|g|b] to change the color, defaults are 0)

I noticed that, for high values of "rot", I get fairly large
"titles" in the corners where the texture doesn't match the rest:

When modulating "zoom", I can put them to good use, but they look
a little odd when running with fixed zoom/rot and a "crowded"
screen. Bug or feature ?
