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!
Currently this is only being used for draw operations that are not automap related, i.e. DrawLine, DrawPixel and FillSimplePoly are not subjected to it.
All our continuous integration targets have no problems with C99 isnan() macro but on Ubuntu 16.04 compilation fails
It appeared that some implementation of C++ Standard Library may undefine bunch of C macros to avoid conflicts with own declarations
- 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,
I did not implement an equivalent to SBARINFO's DrawKeyBar. This is too limiting because it needs to consider any possibility. It really is easier to let a mod implement this itself and custom adjust it to its needs.
- fixed some stuff, in particular use DrawInventoryIcon to get smarter icon lookup.
Fullscreen HUD done with the exception of key and inventory bar. I also used the opportunity to make it a bit more resistant against badly designed inventory icons.
- 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
