Fix grid visualizer offset bug

Bump to Kotlin 1.9

Reverts part of 426a4a6.

- Create new TextureBuffer instead of calling `TextureBuffer.put` every sample
  - otherwise this mutating the `position` field in Javascript (see kgl.Buffer.put)
- Populate 4 frequency buckets of different periods representing low, lomid, mid, hi signals
- Change interpolation to GL_NEAREST (might not be what we want, but then it gives precise values)
- Change history to power of 2, as webgl prefers power-of-two-sized textures
- Tested with pinkyJvm using blackhole as well to make sure this doesn't totally break jvm version

Remove commented ode.

Fix image upload dropzone

Add new BAAAHS shader, mockup BeatInfo utilities for shadertoy

nother shader

New distortion shader: Moiré's Bad Trip

Bump to kgl 0.6.2.

* Bumped shadow jar plugin to 8.3.0.
* Removed -Djava.awt.headless=true java arg and JOGL deps, not needed.
