Ouputing selectionId to ID buffer

In order to be able to output it to the ID attachment in G buffer and use it for label placement
WIP: interfacing selections from ChromatinViewport to LabelLayoutGener.


WIP: im just confused


Redo interfacing layout generator with current selections

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
Computing selection ID information for bins and sending to gpu write

Doesn't work at this point (still getting zeroed out buffer values in shader)
Guess I figured out the problem
