Sorry for the bad english, I really should have rested a little before
writing. I hope you still understand it :-/

> It works by sampling (number of samples configurable) the image and
> drawing a point cloud of those sampled data. An
> option to use full resolution is available but is slow with high res
> image and both waveform and vectorcope pannel
> expanded)
> Saving the statistic data was too much data and too slow, if using
> subsampled data is not ok for preview. Calculating
> an image of the scope and only displaying it as a opengl texture seems
> be the best way to go (more like the sequencer
> scopes). For what it is worth: after effect seems to use a similar
> subsampling method.
> Further (if design is ok):
> -some speed optimisation
> -polish aesthetic
> -zoom in/out with out of range float support
> -colorspace linear and srgb (for histogram too)
