Shader editor - daveRandomRange GLSL function by design allows only one random number per pixel. Repeating the function gives the same float number.

function doesn't have a variable tracking how many times the function was called per one pixel, resulting in giving the same result multiple times.

My thoughts on how to fix that:
To not change something many people are familiar with, I would add seed input which is cancelled out when It's equal to 0.
I have no idea how to replace it, so I guess there needs to be a custom prng with 4 float inputs.

so the solution is to change the seed based on how many times the function is called.
currently, the seed is defined by
r = (gl_FragCoord.x * 50.25313532) + (gl_FragCoord.y * 21.5453) + u_timer;
we just have to add a term howManyTimesTheFunctionHasBeenCalled * someRandomLongConstant

actualy, it seems like it only ever returns some sombination of minvalue and max value. I don't understand why it was made the way it was
