## UI explanation
The firs unnamed input box is either search (google) or URL starting with http/https
Go instructs browser to navigate to the url or perform search
Bk is History Back
W is width in pixels, adjust it to get rid of horizontal scroll bar
H is height in pixels, adjust it to get rid of vertical scroll bar.
It can also be set to 0 to produce one very tall image and use
client scroll. This 0 size is experimental, buggy and should be
used with PNG and lots of memory on a client side.
S is scale or zoom
C is colors, for GIF images only (unused in PNG)
K is keystroke input, you can type some letters in it and when you click Go it will be typed in the remote browser.
Bs is backspace
Rt is return / enter
< ^ v > are arrow keys, typically for navigating a map, buggy.
## Minimal Requirements
* Server/Gateway requires modern hardware and operating system that is supported by [Go language](https://github.com/golang/go/wiki/MinimumRequirements) and Chrome/Chromium Browser, which must be installed.
