Print a message when status bar class defined in GAMEINFO is missing or when it's not derived from BaseStatusBar
Validate internal status bar classes for basic consistency in Debug configuration
(cherry picked from commit 907ce777a3)
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.
- finished work on the Doom status bar. I also took the opportunity to fix the layout of the inventory bar which is a bit broken in SBARINFO.
- tuned the selection rules for deciding what creates the status bar, so that the most recent definition that can be found is chosen.
- got rid of the image list in the Doom status bar. The cost of the texture lookup is mostly irrelevant here so clearer and shorter code is preferrable.
- moved the box fitting code from DrawTexture into the native function to have all coordinate calculations in one place which is necessary to implement proper alignment default handling. Without higher level functions altering positioning the default can be set to automatic alignment determination, i.e. the value's sign decides where something is placed. Of course for special cases this can be overridden.
- use ANIMDEFS to animate the inventory arrow,
- better handling of ForceScale for the fullscreen HUD that doesn't mess around with CVARs.
- moved the mug shot into the status bar, because this is global state that needs to be shared between different pieces of code which want to display a mug shot.
- SBARINFO should work off the current status bar settings instead of the ones stored in its script object
- replaced Inventory.DrawPowerup with a GetPowerupIcon method so that the calling code can handle the drawing and apply its own rules. This was a major design flaw of allowing the inventory items to handle the drawing themselves, because they were unable to adjust to different HUD frontends. Note that any mod that overrides DrawPowerup will not draw any icon that expects to be handled that way!
- the alternative HUD now has its own, separate drawer that obeys the AltHUD's rules, and not the ones of the normal fullscreen HUD.
- the standard drawer has been scriptified as a virtual function.
- Both drawers now handle positioning of the icon inside its assigned box themselves instead of trusting the powerup item to do it correctly.
- DTA_HUDRules and Screen.DrawHUDTexture are to be considered deprecated because both do not integrate into the redesigned HUD code.
This means that with the exception of 3 pointers the DrawTexture interface only accepts numeric values now.
Still need to get rid of the last 3 to have this ready for scripting.
