raylib-sys 6.0.0

//! WS4a: prove the Memory platform initialises windowless and renders into a
//! readable in-memory framebuffer. Only built/run with `--features software_renderer`.
//!
//! Framebuffer readback mechanism (confirmed for WS4b):
//!   `LoadImageFromScreen()` calls `rlReadScreenPixels()` which calls
//!   `glReadPixels()` — implemented in rlsw (the software-renderer GL shim).
//!   After `EndDrawing()` / `SwapScreenBuffer()`, the rlsw framebuffer contains
//!   the rendered pixels and `glReadPixels` returns them correctly.
//!   The platform.pixels buffer in rcore_memory.c is a secondary copy written
//!   by SwapScreenBuffer; `LoadImageFromScreen` reads directly from rlsw, not
//!   from platform.pixels.
//!
//! Minimal feature set required to build+run this test:
//!   --no-default-features --features software_renderer,SUPPORT_MODULE_RTEXTURES
