MAX - Add sliders/options in start marker for swimming!

[fearlesswee]

As it stands we cannot customize swimming behavior without having to dive into the Lua script. It would be nice to have some configurable options here, such as:

• Swimming speed (Right now the swim speed is so extremely sluggish that it might as well not exist as you can't really make use of it in a level, especially when combined with the following issue:)
• Lung capacity/drown time (You drown quite quickly underwater, especially when combined with how slow you swim. Going more than a foot below the surface is ill-advised since you will struggle to rise in time once you start drowning.)
• Various drown damage settings (how often drown damage is taken whilst drowning, how much damage is dealt each time, whether or not damage taken from drowning will be "refunded" once you get some air, etc.)

This also isn't directly related, but it would be nice to have a Lua command and/or a behavior script for oxygen refills we can place underwater, like collectible airtanks that reset the player's lung capacity when collected.

And whilst on the topic of swimming, now that underwater is officially recognized as a valid location for gameplay (finally!), I'd like to remind TGC/Lee about the issues with the water shader: #1401

There are also some significant water shader improvements in the latest builds of Wicked Engine. Wicked did drop support for DX11, but it may be possible to backport from DX12 to DX11 for MAX?

Going through old requests of mine; while we can adjust swimming speed to be something more useful, we still can't adjust things like the player's "lung capacity" (how long they can stay underwater) outside of .Lua, and other features like drown damage "refunding" when you get air. I think this should remain open as a feature request.
