currentUILevel is now primaryLevel.
For ZScript, currentVMLevel was added. This is also exported as 'level' and will change as needed.
This also means that no breaking deprecations will be needed in the future, because in order to sandbox a level only 4 variables need to be handled: level, players, playeringame and consoleplayer.
The remaining global variables are not relevant for the level state.
The static 'level' has been mostly removed from the code except some places that still need work.
UI always runs on the primary level, so this does not need the ability to operate on multiple levels. Additionally, this can later be set to null when running play code so that scope violations result in an abort.
This allows using the UI scale or its own value, like all other scaling values.
In addition there is a choice between preserving equal pixel size or aspect ratio because the squashed non-corrected versions tend to look odd, but since proper scaling requires ununiform pixel sizes it is an option.
- changed how status bar sizes are being handled.
This has to recalculate all scaling and positioning factors, which can cause problems if the drawer leaves with some temporary values that do not reflect the status bar as a whole.
Changed it so that the status bar stores the base values and restores them after drawing is complete.
This would cut off overlong names and the handling for status bars with protruding elements was far too simplistic and worse, making assumptions based on game mode.
It now uses a virtual function to query the status bar itself for returning this information so it can be overridden and uses V_BreakLines to split the text if it is wider than the display.
This is necessary because the hardware accelerated renderers will hide the problem, but with pure software rendering to a locked hardware surface, like DirectDraw can result in a crash.
Note that ANY mod that gets caught in this did something wrong!
