+# Triad sizes are given in horizontal terms, so we need geom_max_aspect_ratio
+# to relate them to vertical resolution.  The widest we expect is:
+#   geom_max_aspect_ratio = 4.0/3.0  # Note: Shader passes need to know this!
+# The fewer triads we tile across the screen, the larger each triad will be as a
+# fraction of the viewport size, and the larger scale_y5 must be to draw a full
+# num_resized_mask_tiles.  Therefore, we must decide the smallest number of
+# triads we'll guarantee can be displayed on screen.  We'll set this according

+#   scale_y5 = geom_max_aspect_ratio * min_scale_x
+#   # Some code might depend on equal scales:
+#   scale_x6 = scale_y5
+# Given our default geom_max_aspect_ratio and min_allowed_viewport_triads:
+#   scale_y5 = 4.0/3.0 * 2.0/(341.33333 / 8.0) = 0.0625
