[Feature]: Render methods

Describe the feature/enhancement you need

The inclusion of features to control the rendering for grabbing frames, that is:

1. The ability to control time, so for a css animation of 4s, when I specify "give me the frame in second 2" the rendering should render immediately the second n 2 and stop.
2. The ability to control input, so I can say "now act like there's a mouse left down in specific XY" or keyboard input.
3. The ability to grab the rendering at a specific size and/or scrolling as a bitmap.
4. The ability to query the size of the entire scrolling so the bitmap can be grabbed in parts.

The scenario/use case where you would use this feature

Within my video editor. It would be nice to have e.g. an animated HTML chart which will be converted with my app in frames and rendered in a MP4.

How important is this request to you?

Nice to have. Currently I have to grab the screen with video capture. This feature would allow me to include direct HTML in my app and reuse known JavaScript libraries.
