We now use dlsym() to check for XMesaSetFXmode() at runtime. If we find XMesaSetFXmode() all DGA code is disabled so it won't clash with Glide (Glide on Voodoo 3 uses DGA internally...) For XMESA we now check the MESA_GLX_FX environment variable at startup to detect whether we are started in windowed or fullscreen mode, and then set the cvar vid_glx_fullscreen to match that.
