Subject: [PATCH] libs: replace libepoxy-stub with real libepoxy
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The libepoxy-stub provided a hardcoded stub that returned 0/NULL for
every epoxy_egl_extension_supported, epoxy_has_gl_extension, and
epoxy_gl_version call, plus a fake epoxyConfig.cmake. KWin and Qt6
Wayland code paths were never able to detect GL/EGL extensions or
negotiate GL versions, which broke the KWin rendering pipeline silently.

Replace it with the real libepoxy (anholt/libepoxy fork) — the full
upstream C source, built against Mesa EGL/GLES2, that registers
epoxy::epoxy in CMake, provides libepoxy.pc, and produces the real
epoxy_gl_version / epoxy_has_gl_extension / epoxy_egl_*_supported
runtime values. Recipe bumped to 0.2.3 with v6.0 2026 description.

Also: protected-recipes.toml [libs] no longer lists the stub.
