Arcane eye UI improvement ... shrink or transparent

[Jahf]

So now that I'm using Merkul's Second Eye as a Timewarden I've got eyes popping up all over the place (yay for clones).

But it hides the entire square pretty significantly.

If transparency is easy in the TEngine, cool.

If not, maybe scale it down to 1/3rd size?

I like the sound of an Atomic Purple Arcane Eye.

It can be a little odd at times getting to see the enemy under it, which is pretty ironic considering what it's supposed to do.
