choose_pixel_format()

void eglGraphicsStateGuardian::choose_pixel_format	(	const FrameBufferProperties &	properties,
		X11_Display *	display,
		int	screen,
		bool	need_pbuffer,
		bool	need_pixmap
	)

Selects a visual or fbconfig for all the windows and buffers that use this gsg.

Also creates the GL context and obtains the visual.

egl_is_at_least_version()

bool eglGraphicsStateGuardian::egl_is_at_least_version	(	int	major_version,
		int	minor_version
	)		const

Returns true if the runtime GLX version number is at least the indicated value, false otherwise.

void eglGraphicsStateGuardian::get_properties	(	FrameBufferProperties &	properties,
		bool &	pbuffer_supported,
		bool &	pixmap_supported,
		bool &	slow,
		EGLConfig	config
	)

Gets the FrameBufferProperties to match the indicated config.
