Dæmon window is empty and undefined until shaders are compiled

On slow hardware it can take a long time and the window displays garbage for all this time…

Maybe there is a way for SDL to fill the window with black before this:

Daemon/src/engine/renderer/tr_init.cpp

Lines 333 to 338 in 6b94e2e

	// handle any OpenGL/GLSL brokenness here...
	// nothing at present
	#if defined( GLSL_COMPILE_STARTUP_ONLY )
	GLSL_InitGPUShaders();
	#endif

Or even earlier, right after that:

Daemon/src/engine/sys/sdl_glimp.cpp

Lines 702 to 719 in 6b94e2e

	window = SDL_CreateWindow( CLIENT_WINDOW_TITLE, x, y, glConfig.vidWidth, glConfig.vidHeight, flags );
	if ( !window )
	{
	logger.Warn("SDL_CreateWindow failed: %s\n", SDL_GetError() );
	continue;
	}
	SDL_SetWindowIcon( window, icon );
	glContext = SDL_GL_CreateContext( window );
	if ( !glContext )
	{
	logger.Warn("SDL_GL_CreateContext failed: %s\n", SDL_GetError() );
	continue;
	}
	SDL_GL_SetSwapInterval( r_swapInterval->integer );
