core:math/noise noise.noise_2d(seed, {0,0}) is discontinuous and the same value regardless of seed.

Context

Please provide any relevant information about your setup. This is important in case the issue is not reproducible except for under certain conditions.

• Operating System & Odin Version: Odin: dev-2023-08-nightly:9453b238 OS: Windows 11 Professional (version: 22H2), build 22621.2283 CPU: AMD Ryzen Threadripper PRO 3955WX 16-Cores RAM: 65388 MiB

Expected Behavior

New values for different seeds when using 0,0 for the coordinate. No discontinuity at 0.0 .

Current Behavior

The result of noise.noise_2d(seed, {0,0}) is always 0.00000000 or -0.00000000 regardless of the seed and leads to a discontinuity.

I haven't tested any of the other noise functions to see if they have the same issue

Good catch. Makes me wonder if that holds true for the C noise library it's based on, or an artefact of @NoahR02's port that we missed at the time.

Well there is this open issue for it so looks like it's in the original C noise library too: https://github.com/KdotJPG/OpenSimplex2/issues/21
