Test and feedback much appreciated :)

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

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)
