render/invalidate small rectangle

[sidorares]

afaik at the moment there is no way to render small rectangle on screen, .render() redraws the whole terminal. For applications like vnc this makes big performance hit as often I need to update small portions of the screen (e.i cursor movements). Is something like render(x,y,w,h) in the roadmap?

Sounds like a great feature! And not too hard to implement off the top of my head. Feel free try whip up a patch, or I'll try to get to it when I get a chance.

Yes, should be not too hard. Whoever first :) might have some time this evening.

Souldn't be better being .render() internally called automatically by canvas object methods? This could just be wrapped... Another option is to have an offline mode where you could exec some methods and later call .render() manually, this would allow to have a transparent API.
