Can not leave texture object null

[skbizport]

Shader might check for a boolean variable for either using texture or color. So, texture object need not be created during setup.
Current code does not handle it. It tries to call uniforms[ name ].data.init() in compiler.createUniforms(..) function

I'm not really following... A texture is a texture and you use a vec3 or vec4 if you like a color. Or? :)
