Subject: [PATCH] Fix use of glXChooseFBConfig.

Based on https://www.opengl.org/sdk/docs/man2/xhtml/glXChooseFBConfig.xml
the last parameter of the attributes array must be None (which == 0).

Confusingly, this is different from GLX_NONE, which is non-zero.

This fixes webgl context creation on some drivers, in particular nVidia proprietary drivers but probably others too.
