+This fixes (workarounds) gridblock drawing. The original code drew the
+whole area, and then started at the top overdrawing the first block and
+thus missing one at the button (or reversed if reversed ...).
+
+This changes the behaviour to always draw downwards (or reversed) and thus
+at least yielding the correct gridblocks - although the performance is
+bad (many block fills ...).
