- Add configurable GLEW_USE_EGL option (default OFF) to match wxWidgets - Explicitly set wxUSE_GLCANVAS_EGL=OFF for vendored wxWidgets build - Add compile-time check to detect EGL/GLX backend mismatch between GLEW and wxWidgets, preventing silent rendering failures The bug occurred when GLEW was compiled with EGL support (using eglGetProcAddress) but wxWidgets created GLX contexts. This mismatch caused OpenGL function pointers to fail loading, resulting in blank 3D model preview. Co-authored-by: SoftFever <softfeverever@gmail.com>
