speed looks pretty fine, but there seem to be still racing conditions: getting very jittery results

I believe this anyway will be reverted because adding "fake" data points is a stupid thing to do...

Doesn't work at this point (still getting zeroed out buffer values in shader)

Prepared for final version, for now it doesn't work only because I'm not getting the right IDs in the ID attachment of g buffer

In order to be able to output it to the ID attachment in G buffer and use it for label placement

There's still a bug where the behaviour randomly switches for some reason

but is extremely unstable plus i had to do some magic constants to get the position to match

The issues was in initial contour seed value.
It also seems that there is some scaling problem

Ideally I'd like to unify it so that you don't have to have different versions for regular/float textures and different formats...
