GHOST_X11_GL_GetAttributes()

int GHOST_X11_GL_GetAttributes	(	int *	attribs,
		int	attribs_max,
		bool	is_stereo_visual,
		bool	need_alpha,
		bool	for_fb_config
	)

Utility function to get GLX attributes.

Parameters

for_fb_config

There are some small differences in #glXChooseVisual and #glXChooseFBConfig's attribute encoding.
