'''OpenGL extension OES.surfaceless_context

This module customises the behaviour of the 
OpenGL.raw.GLES2.OES.surfaceless_context to provide a more 
Python-friendly API

Overview (from the spec)
	
	Applications that only want to render to framebuffer objects should
	not need to create a throw-away EGL surface (typically a 1x1
	pbuffer) just to get a current context.  The EGL extension
	KHR_surfaceless_context provides a mechanism for making a context
	current without a surface.  This extensions specifies the behaviour
	of OpenGL ES 1.x and OpenGL ES 2.0 when such a context is made
	current.

The official definition of this extension is available here:
http://www.opengl.org/registry/specs/OES/surfaceless_context.txt
