[ZMeter] graph choice, transparency and sticky borders

Hello,

I used Freemeter for monitor my bandwidth, but I see on your website ZMeter.
It very nice and I want to use it, but I have some improvement ideas.

1) Choose what I want to see (Only network, CPU and network, all, etc)
2) The famous transparency !
3) Sticky borders, for better placement on screen corner

Maybe you can implant this in command line options.

Thank You !
Ben
