[1.32] Custom/modified unit classic blob shadows bug.

[Dr Super Good]

Many people are claiming that Classic graphics is missing blob shadows. This is not correct as blob shadows do still exist and work. One can see this in the World Editor when running classic graphics and in melee games.

However there is currently a bug with custom units and blob shadows. For custom units the shadow data fields are not being read/generated correctly in game. For copied unit data this results in all shadow fields being interpreted as 0 values even when defaults are meant to be inherited. For modified unit data this results in any modified shadow field being interpreted as a 0 value irrespective of what the user sets it to.

Attached is a demonstration map showing this problem.

The left Blood Mage (Standard Blood Mage) uses standard unmodified shadow data so has a working blob shadow.
The right Blood Mage (Custom Blood Mage) is a copy and paste of the standard one. It appears to be missing its blob shadow in game.
The top Mountain King (Modified Mountain King) is a standard unit with modified shadow data. It appears to be missing its blob shadow in game

A screenshot is provided showing what can be experienced by running the map with 1.32 with Classic graphics. The correct behaviour would be that all 3 units have blob shadows visible, like in World Editor when running Classic graphics.

Note the white square artefacts shown around the Blood Mages in the screenshot is a screenshot only bug. They appear visually fine during actual gameplay.

Newly produced units(Units already placed on the map are normal. lol)
also have a bug that projectile scaling is turned off.
If you turn it back on using a new function(BlzSetUnitBooleanFieldBJ), it works fine.
But shadows seem impossible. As a result of my testing

You can actually intercept a units shadow upon creation to see that they are being created, just with zero width and height. You can replace the broken shadow with your own through code since shadows are just images, although I would prefer an actual fix.
