* Rework HU_UpdatePatch to HU_UpdateOrBlankPatch with a "required" boolean.
* If desired graphic is not present in resources:
* If required is true, return `missingpat`.
* If false, return NULL as before (font compatibility).
* Add an alias with the previous function signature, so you don't need to add a million `true`s everywhere.
* Remove a ton of irrelevant graphics the game attempts to cache only because of code inherited from vanilla SRB2.
* Remove the unused hudinfo system, also inherited from vanilla SRB2.
* Blend tables generated by the game.
* The Color Cube accessibility tool.
* Fixed another stupid typo that got in the way of FF_BLENDMASK working.
* Some minor adjustments for code cleanliness.
All my work thus far on solving the drawflag/renderflag/additive/subtractive conundrum.
Outstandng problems:
* Bad additive/subtractive tables means that they appear opaque except under certain conditions.
* No support for FOFs, Polyobjects, or linedefs in OpenGL yet.
* All OpenGL support mostly done blind, may or may not function in practice.
If nothing else, the hard engineering problems are solved and it's just bug hammering...
* None of the following things (grouped by the fact they fade/slide in) use hardcoded static numbers; they'e now attached to the titlecard ticker.
* Minimap.
* All V_HUDTRANS items. (Not add/sub) - this was previously broken entirely
* FREE PLAY
* Record Attack Input (no longer slides in at all - needs to be visible from start of play.)
* Fixed a rare case where V_SLIDEIN HUD elements would occasionally jump a step too far.
* Adjust several loading strings, and left-align their rendering.
* Don't call HU_LoadGraphics() again (startup cached ALL FONTS twice).
* Adjust when some functions are called during loading to more effectively compartmentalise sections of loading that depend on each other.
* LOADED_ISTARTUPGRAPHICS now comes after SCR_Startup, as we can explicitly guarantee the palette has been loaded after that function.
* Make sure everything closely related to configurations (gamedata, console stuff, etc) which is not directly dependent on anything else is loaded under LOADED_CONFIG - "Load settings" (formerly LOADED_MINIT).
* The `-warp` command line parameter is now checked alongside LOADED_DCHECKNETGAME.
* Don't attempt to draw the loading bar before LOADED_ISTARTUPGRAPHICS, as the palette is not loaded, which means you're wasting cycles on a white screen.
* Resolves#145.
* Increased granularity, to seperate out texture loading and sprite loading from other render structure initialisation.
* Shows small loading string in DEVELOP builds, to show where we can optimise loading times when we're polishing.
* Clean up con_refresh/startup, which got split into two variables in the merge by mistake.
Explanation: NearestColor takes UINT8 inputs, but is being provided a number in the range of 1 to 256(!!) - which means very dark channels were looping back around to 0.
This error might exist in public branches too, because I don't think Encore's wipes would have been changed internally without us knowing.
So for whatever reason it's still giving me a warning about functions in i_threads having duplicate definitions, even though they clearly do not.
I'm completely stumped so I'm just gonna mess with my compile setup....... in the mean time, if anyone else could try to compile it, I'd appreciate it, so we know if it's just my end or if its something else
