Import shader from shadertoy problems

[seb776]

Hello there,

I tried using the ISFEditor to convert some of my shaders to ISF format but apparently there are a few issues
Here's the shader I tried
https://www.shadertoy.com/view/7s2Sz3

The errors I spotted :

• It does not import the common tab (it's probably easy to fix as it simply requires code concatenation)
• When doing multipass shaders, it does not handle multiple functions having the same name (would require a kind of mangling / namespace to the names)
  Here's a detailed list of the errors I got from the editor
