render/invalidate small rectangle

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?

Using createImageData from node-canvas

Any idea on how to get createImageData?

The normal pattern of installing both modules (ansi-canvas & node-canvas) does not work because the "canvas.node" file gets built twice. Then putImageData() does a type check that fails. I assume instanceof is being used, but I cannot seem to find the offending code.

The anti-pattern of requiring a transitive dependency does not work with webpack. Yes.. I really am using webpack for a node module because I am experimenting with WebAssembly and I don't really understand the toolchain yet.

Can't install in Node v0.11.14

Maybe it's due to version of canvas module (1.0.3) specified as dependency in ansi-canvas' package.json , because if I install standalone canvas module (current is 1.1.6) I haven't any problems.

Specifically, I get these errors:
