GPU based vertex selection~

to prevent selecting hidden verts, I test them against a depth texture in the compute shader - works super well!

@acegikmo yup, that’s a good way
@acegikmo I also love Freya who discovered the wonderful (and sometimes scary) world of compute shaders ;)
@aras Been getting into them as well. Aside from some of the specifics it's all pretty intuitive. Data in, texture out.
@Robin_Van_Ee once/if you get into lands of wave/subgroup operations and atomics shenanigans, things can get pretty strange. Before that, yeah intuitive.
