m2SDL showcases

Ports of example programs from the vendored SDL archive (SDL-main/, ignored by git) to GNU Modula-2, running against SDL2.

Showcase Ported from Shows
showcase_clear examples/renderer/01-clear/clear.c renderer, per-frame clear color, MathLib0.sin fade
showcase_rectangles examples/renderer/05-rectangles/rectangles.c draw/fill rects, rect arrays via ADR, integer scale math
showcase_primitives examples/renderer/02-primitives/primitives.c fill rect, point cloud (libc rand), outline, X lines
showcase_snake examples/demo/01-snake/snake.c full game: packed board, food, keyboard (SDLKey, PollM2Event)

All three are public-domain originals; adaptation notes (SDL3 to SDL2 API renames, float to integer rects, callback to main-loop shape) live in each file header.
