Get the frame that would be displayed.
E.g. so that it can be superimposed over the output of another PostProcessor, see setSuperimposeVdpFrame().

Sets up the "abcdFrame" variables for a new frame.
TODO: The point of passing the finished frame in and the new workFrame out is to be able to split off the scaler application as a separate class.
finishedFrame | Frame that has just become available. |
time | The moment in time the frame becomes available. Used to calculate the framerate for recording (depends on PAL/NTSC, frameskip). |

Set the VDP frame on which to superimpose the 'normal' output of this PostProcessor.
This is similar to the method above, except that now the superimposing is done before scaling. IOW both frames get scaled.

Set the Video frame on which to superimpose the 'normal' output of this PostProcessor.
Superimpose is done (preferably) after the normal output is scaled. IOW the video frame is (preferably) left unchanged, though exceptions are e.g. scalers that render scanlines, those are preferably also visible in the video frame.

Create a raw (=non-post-processed) screenshot.
The 'height' parameter should be either '240' or '480'. The current image will be scaled to '320x240' or '640x480' and written to a png file.
