supporting texture input

[Makio64]

Hi !

Thanks for this great tool, it will be awesome if it support texture uniforms so we can made it works with all our shaders, like:
--channel0 texture.jpg
--channel1 music.mp3

Thanks again!

Feel free to add the feature and make a pull request! I won't have the time to do this one myself.

Hello,

I am using the version with the channels added - the channel wrapping does not behave as it does on shader toy even though tex.wrapping = 'repeat', it behaves more like 'clamp'.

All examples on shade toy that utilise repeat express the same issue. https://www.shadertoy.com/view/Xdl3D2 for example outputs differently in video than in the shadertoy renderer.

Is there a way to rectify this or at least point me in the right direction.

I really hope I can resolve this. Many regards Mark.
