Add lowQuality param to IWidget.draw (#843)

Currently widget needs to get access to `LGraphCanvas` instance to know
whether the canvas is rendering in low quality (Zoomed out). Usually
canvas object is obtained from `ComfyApp` instance.

This PR passes the lowQuality value to `IWidget.draw` to decouple the
dependency on `LGraphCanvas`.
