Added credits display to trade screen
Fixed bug in inventory screen where a failed drag from a cargo bay would make the item disappear until a refresh is triggered
Changed behavior of Escape key to exit menu if a menu is open
Fixed zone map gravity isolines to correctly track maximum gravity depth
Refactored orbit and planet data to replace reactive variables with regular ones
Removed hard zone boundaries
Fixed stuff that broke because of hard zone boundary assumption (stardust placement, vertical fog)
Added a skybox!
Removed density-based albedo boost (_TintExponent) to improve perceptual uniformity at different step sizes, reconfigured shader to achieve / surpass previous looks and performance
Cell Brush has a material editor now to enable variant selection
Enabled Caching Shader Preprocessor
Moved raymarching loop into CloudShader
Get environment settings from game manager to enable configuration / variation
Introduced slope-based nebulae damping and volumetric flow
Hid optional volumetric features behind preprocessor branches
Created shader variants selected by global keywords for all shaders depending on volumetrics
Environment settings used to configure shader variant selection
Moved dynamic lighting settings to own subclass
Dynamically adjust gravity map isoline contour depth range according to zone contents
Improved volumetric flow performance by orders of magnitude
Cleaned up old raymarching support code
Moved asteroid height calculation to vertex shader
Manual culling for asteroid field render update
Applied nebula lit shader to "planets" and asteroids
Modified gas giant shader to accept nebula lighting and to be a bit less crappy in general
Fixed raymarching depth sampling perspective distortion
Added new clouds shader with improved raymarching loop
Currently only being used in main menu (rest is coming right up!)
Removed WWise (it's nice, but all it's doing is throwing exceptions rn since we ain't about to get a license)
Fixed towing system
Tweaked Nebula Flow (a lot)
Extracted environment appearance settings into ZoneEnvironment data structure
Stardust particles now follow global flow field
Fixed various bugs caused by triggering wormhole animation multiple times
Sector -> Galaxy
Fixed bug in hostility system; deserialized entities' PresencePermitted was silently throwing an exception (due to Faction being null during initialization) and thus never updating in response to security level changes
Worked a bit on story processing
Map icons now have a constant size independent of zoom level
Galaxy Map now displays zone properties when clicking on a zone
Zone generator now uses half of nebula density, means smaller and more varied zones
Stations will refuse docking to entities with insufficient clearance
