86     interpreted using the current sample locations.
150     Each framebuffer has a set of default sample locations, depending on the
154     programmable sample locations, which may be used instead of the default

165     locations values in a framebuffer, where <N> is the value of
168     [0,1], corresponding to the x and y locations respectively in GL pixel

377     (3) Should programmable sample locations affect non-multisample rendering?
379     RESOLVED: No, the programmable sample locations only apply to multisample
385     sample locations.

405       you effectively delete all programmable sample locations and revert to
406       default locations via programming a new location using a NULL pointer.
