Variable Tiny_Number not works well

[johypark]

Hello,

Firstly, thank you for porting qef to hlsl.

I'm watching this code to implement dual contouring.
I added qef.cginc in my unity project, but something wrong when I use this file.

I found that Tiny_Number variable is not static.
After I change it static and test, It looks strange either.
So I search some references and changed Tiny_Number bigger, like 1, it works well.
But number 1 is pretty big.

Is there any bug in this ported code?
