MI_FireRing adds missiles MIS_FIREWALL with TARGET_BOTH and src equals
to either player ID, or -1 if Fire Ring is casted as trap. This has
consequences:
1. Because TARGET_BOTH MonsterMHit was called, as it usually called for
Firewalls. During this calls reference to Player gets garbage data (id
-1). This may miscalculate:
- no heal flags
- knockback flags (already fixed in this PR)
- unsquelch position.last
2. drops ear for firewall flame originating from Fire Ring from trap
Fix:
- Separated TARGET_BOTH from IsTrap for monsters to ensure TryHitMonster
will get passed TrapMissile (MonsterTrapHit) is called instead.
- added additional condition for earflag
The version in Ubuntu 22.04 comes without `ConvertUTF.{h,c}`.
We actually do not need `ConvertUTF.{h,c}` and starting from
v4.19 it is possible to tell SimpleIni to not include it
by setting `SI_NO_CONVERSION`.
Sets `SI_NO_CONVERSION` and raises the minimum required SimpleIni
version to 4.19.
Reduces the size of the `PathNodes` array from 28 KiB to just 8 KiB.
Also reduces the size of `pnode_tblptr` from `300 * sizeof(void *)` to
`300 * 2` bytes.
* Add MakeRectangle helper to convert from SDL_Rect
* Add Rectangle::inset method for shrinking a rectangle
Turns out some of the other use cases I though this could apply to were actually doing something based on a fixed region
* Simplify initialisation of settings menu rects
* Use explicit typecasts to force signed char comparisons
Avoids warnings about tautological comparisons (either the >= 0 comparison for ARM/PowerPC or the <= 127 comparison for x86*)
* Remove unused function
