Fluid Limit

[wereretot]

Increase fluid limit as it is too low for higher-end hardware.

Fluid limit should no longer be hardcoded but become a level setting, allowing levels to increase fluid limits when needed, while keeping old levels using old limits as default to not break things.

On Windows 10, modifying the fluid limit to be much greater works, but the extra fluid particles don't render for some reason (they still interact with objects though). This behavior is similar to something I remember messing with a while back, Google's LiquidFun extension of Box2D (to see what I mean go to https://google.github.io/liquidfun/ and change it from "Dam Break" to "Drawing Particles" and drag the mouse around the walls a bunch). Perhaps since Principia uses Box2D it has the same issue?
