Keep the existing non-smoothed scaling behavior while moving tile and asset resizing off zoomSurface(). This preserves current alpha and colorkey handling and gives the SDL3 port a smaller graphics dependency surface.
Generate rotated bullet surfaces with a local nearest-neighbor path instead of rotozoomSurface(). This keeps the existing per-bullet caching model in place while removing the last runtime transform dependency from SDL2_gfx.
Stop including SDL2_rotozoom headers, remove SDL2_gfx from configure checks, and update CI packages to match the new dependency set. The codebase now builds and runs without SDL2_gfx, clearing the graphics-side blocker for the SDL3 migration.
- we'll move up to 2.0 when hitting full SDL3 port

Ok, SDL2 port seems complete, and cleaned-up some of the intermediate compatibility-wrappers. Testing (on Linux) shows all working as it should be. |

Ported old SDL1.2 interface to using SDL2 (with help from OpenCode(GPT-5.3-codex)).
This is meant as an intermediate step to porting this to SDL3.
Seems to work completely, at least on Linux. (Deferring cross-builds until SDL3 migration is complete).
