---
---Converts a color from gamma-space (sRGB) to linear-space (RGB). This is useful when doing gamma-correct rendering and you need to do math in linear RGB in the few cases where LÖVE doesn't handle conversions automatically.
---
---Read more about gamma-correct rendering here, here, and here.

---
---Gets the seed of the random number generator.
---

---
---Gets the current state of the random number generator. This returns an opaque implementation-dependent string which is only useful for later use with love.math.setRandomState or RandomGenerator:setState.
---

---
---Converts a color from linear-space (RGB) to gamma-space (sRGB). This is useful when storing linear RGB color values in an image, because the linear RGB color space has less precision than sRGB for dark colors, which can result in noticeable color banding when drawing.
---
---In general, colors chosen based on what they look like on-screen are already in gamma-space and should not be double-converted. Colors calculated using math are often in the linear RGB space.
