MSAA 2x on Mali - GLES

Hi,

Although OpenGL ES  has mechanisms to query the maximum number of samples (with a min of 4 on GLES 3.1), there's no requirements for the opposite. Is there any expected behavior on Mali GPUs (at least from Midgard onwards and inclusive) if the amount of samples specified is 2x? Does it fallback to no samples at all or perhaps up to 4x? Or do I need to assume it's undefined behavior. (disclaimer: I'm aware of your recommendation of using 4x on Mali though)
