+ report (via 'mainDeltaSize') the delta that it wanted in the *last pass
+ of the loop before that item was frozen*.
+
+ Here's what goes on in each pass (and the tentative deltas)
+ * PASS 1
+ - Available space = 120 - 10 - 20 - 30 - 0 = 60px.
+ - Sum of flex values = 1+1+2+16 = 20. So 1 "share" is 60px/20 = 3px.
+ - Deltas (space distributed): +3px, +3px, +6px, +48px
+ VIOLATIONS:
+ item0 is now 10+3 = 13px, which under its min
+ item1 is now 20+3 = 23px, which under its min
+ item3 is now 0+48 = 48px, which over its max
+ - the magnitude of max-violations (how far we're out of bounds) exceeds
+ magnitude of min-violations, so we prioritize the max-violations.
+ - So we freeze item3 at its max-width, 20px, leaving its final "desired"
+ mainDeltaSize at +48px from this pass.
+
+ * PASS 2
+ - Available space = 120 - 10 - 20 - 30 - 20 = 40px.
+ - Sum of flex values = 1+1+2 = 4. So 1 "share" is 40px/4 = 10px.
+ - Deltas (space distributed): +10px, +10px, +20px, +0px.
+ VIOLATIONS:
+ item0 is now 10+10 = 20px, which is under its min
+ - So we freeze item0 at its min-width, 35px, leaving its final "desired"
+ mainDeltaSize at +10px from this pass.
+
+ * PASS 3
+ - Available space = 120 - 35 - 20 - 30 - 20 = 15px.
+ - Sum of flex values = 1+2 = 3. So 1 "share" is 15px/3 = 5px.
+ - Deltas (space distributed): +0px, +5px, +10px, +0px.
+ VIOLATIONS:
+ item1 is now 20+5 = 25px, which is under its min
+ - So we freeze item1 at its min-width, 28px, leaving its final "desired"
+ mainDeltaSize at +5px from this pass.
+
+ * PASS 4
+ - Available space = 120 - 35 - 28 - 30 - 20 = 7px.
+ - Sum of flex values = 2. So 1 "share" is 7px/2 = 3.5px
+ - Deltas (space distributed): +0px, +0px, +7px, +0px.
+ VIOLATIONS:
+ None! (So, we'll be done after this pass!)
+ - So we freeze item2 (the only unfrozen item) at its flexed size, 37px,
+ and set its final "desired" mainDeltaSize to +7px from this pass.
+ - And we're done!
