Splash filter doesn't work with colors that have all RGB values at less than 0x60

When using the Repeatable Wounds macro:

let params =
    [{
        filterType: "splash",
        filterId: "mySplash",
        rank:5,
        color: 0x990505,
        padding: 0,
        time: Math.random()*1000,
        seed: Math.random(),
        splashFactor: 1,
        spread: 1,
        blend: 1,
        dimX: 1,
        dimY: 1,
        cut: false,
        textureAlphaBlend: true,
        anchorX: 0.5,
        anchorY: 0.5,
    }];

The color 0x990505 creates a red bloodstain.

The color 0x600505 creates a dark red bloodstain.

The color 0x590505 creates an invisible bloodstain, and isn't visible at all. This is a bug!

Same bugs happen with e.g. 0x000060 vs 0x000059.

@Feu-Secret, not sure if you've looked at this previously.

https://github.com/Feu-Secret/Tokenmagic/blob/master/tokenmagic/fx/glsl/fragmentshaders/splash.js#L80

This threshold is what is causing it to cut off. I've experimented with it and can't see any reason why it cuts off arbitrarily at 0.35?

Exposing that threshold as a uniform, removing the if-block entirely or adding an additional setting to not early out would all solve this issue. Any preferences?

[Edit] Removing the block doesn't work when the colour is pure black. if (splashed == vec3(0.0)) does work though.

Thank you @OsiJr to take care of this issue!
