HUD sprite scaling

[Iniquitatis]

Discussion: viewtopic.php?f=4&t=65943

Not yet sure, if this is a feature request or a bug report, but in any case there's no proper option to control scaling/stretching of active weapon's HUD sprite*, which could help to prevent that 1:1.2 aspect ratio correction.
Or HUD sprite just doesn't respect the PixelRatio property from the MAPINFO** lump.

* — Or PSprite?
** — Seems less logical, because this is a map property.

Finally got around to making a PR for this, on a whim: https://github.com/coelckers/gzdoom/pull/1508

Yeah, we've got A_OverlayScale now, but it's not as convenient and doesn't work in the software renderer (for all 3 of us that use it ). More details n' such in the PR.

Thanks Xaser. Yes, I'd still very much like a way to simply just scale the weapon sprite without messing with overlays.

Maybe that's not directly related but weapon sprite scaling looks weird when in resolutions with aspect ratios less than 1.3. E.g. on a portrait 1024x1280 hand with pistol occupies 1/3 of the screen. This isn't intended, right?
