Well, propably it's easier to leave java.awt.Cursor off from general 
GraphicsAPI than prove that it doesn't load any AWT classes, which may 
cause the AWT init :/

So...

"Somewhere"? In the javadoc of GraphicsAPI.Window.setCursor()?

Although, we should check somewhere that Cursor corresponding to given
string exists. Should it throw just Error or some existing/new exception 
if proposed cursor doesn't exist?

Should that check be done in both AWTScreen and GLScreen distinctly or 
should we use our own Cursor wrapper class for this? And then we would 
be just reinventing then wheel / the java.awt.Cursor :/

Yes. This is so simple, that it could exists anyway.
