131     Each framebuffer has a set of default sample locations, depending on the
135     programmable sample locations, which may be used instead of the default

360     RESOLVED: No, the programmable sample locations only apply to multisample
366     sample locations.

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