I think the description is not quite correct. I believe something like Selects random points from the current strokes selection would be more accurate.

Not sure what happened here, maybe some added spaces? in any case, it should not be in the PR.

I reverted this change and will push now, but this was because the file is currently missing a new line at the end. Shouldn't there be one?

Ah! I missed that. Yes it should have one, so you can actually keep this change.

Did I understand correctly that he selects different drawings identically, since their index is not taken into account in the noise?

@mod_moder That is a good observation! I think what we could do is something like ed::curves::select_random(..., seed + drawing_index, ...);.

@mod_moder Right, better to avoid seed collisions and use BLI_hash_int_2d(seed, drawing_index).
