Description

Currently we render everything within the normal event loop.

It would be nice if we have more flexibility:

  • move communication of the rendering response (which is potentially large) into a resource (so that it doesn't block event loop)
  • move rendering work into a resource (so that it doesn't block the event loop)
  • for WPaintedWidget: allow to keep around the rendering logic client-side (for canvas-based rendering) so that one can re-render client-side after changing the a transformation
  • for WGLWidget: allow to intervene through JavaScript in the rendering logic to do smarter things with what's available client-side
