Tank round count hud indicator overlaps over round type

[Andrew Theel]

HUD pieces overlap one another making it difficult to read.

OK, I looked at HUD stuff when I did the smoke mortars. Knew nothing about HUD canvas stuff before; now I know a bit and should be able to sort this. One issue I noticed was scaling for different screen res, which isn't always done but I managed to get a working scaling system in my smoke icon display.
