+Multiple samples within a pixel can have the same color. ``nr_storage_samples``
+determines how many slots for different colors there are per pixel.
+If there are not enough slots to store all sample colors, some samples will
+have an undefined color (called "undefined samples").
+
+The resolve blit behavior is driver-specific, but can be one of these two:
+1. Only defined samples will be averaged. Undefined samples will be ignored.
+2. Undefined samples will be approximated by looking at surrounding defined
+   samples (even in different pixels).
+
+Blits and MSAA texturing: If the sample being fetched is undefined, one of
+the defined samples is returned instead.
+
+Sample shading (``set_min_samples``) will operate at a sample frequency that
+is at most ``nr_storage_samples``. Greater ``min_samples`` values will be
+replaced by ``nr_storage_samples``.
