In the end there would be two labels created for one selection ID...probably there's some issue with default value in the GPU implementation

already a significant speedup

key was simplifying to 1D access and directly getting UVs from ID buffer

It looks like there's not really a way to optimize this implementation and it will just stay as a reference

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
