Formats the uniform data as needed for feeding the named uniforms values into the shader.
The argument list is a list of pairs of names, and values for the types that match the declared uniforms (i.e. double/int/guint/gboolean for primitive values and `graphene_vecN_t *` for vecN uniforms).
It is an error to pass a uniform name that is not declared by the shader.
Any uniforms of the shader that are not included in the argument list are zero-initialized.
