We already removed it from the online docs with #35132. Currently it can only be "Built-In Types" (Variant types) or "Core" (everything else), which is of limited use. We might also want to consider dropping it from `ClassDB` altogether in Godot 4.0.

Converts the color to grayscale using the following formula:

[codeblock]
|
|
vec3 c = input;
|
|
float max1 = max(c.r, c.g);
|
|
float max2 = max(max1, c.b);
|

float max3 = max(max1, max2);
|

return vec3(max3, max3, max3);

|
|
vec3 c = input;
|
|
float r = (c.r * 0.393) + (c.g * 0.769) + (c.b * 0.189);
