Effect: Minimize calls to configure in default impl.

Browse Source 
In case BaseShaderProgram implementations have an expensive
configure() call, we can only call configure() when absolutely necessary,
aka when the input size changes.

To reduce scope, this doesn't reduce the amount of
configure() calls that may be made outside this class, in
DefaultFrameDroppingShaderProgram and
FinalShaderProgramWrapper.
