Sets a new value for the uniform at uniform_location.
If this pipeline has a user program attached and is later used as a source for drawing, the given value will be assigned to the uniform
which can be accessed from the shader's source. The value for uniform_location should be retrieved from the string name of
the uniform by calling get_uniform_location.
This function should be used to set uniforms that are of type float. It can also be used to set a single member of a float array uniform.
