[shader] Go down to just a single input shader.

This is in preparation for adding child shaders.
Once we have child shaders we can have multiple
images by adding child shaders and changing the
input image.

Also:
 - Moves all the image loading code into ShaderNode.
 - Input image dimensions are now determined by the image
   loaded, instead of being hard-coded.
