Subject: [PATCH 14/45] Remove support for GL_POINT_SMOOTH and GL_LINE_SMOOTH
 antialiasing

These antialiasing techniques have been removed in OpenGL 3.1, they were often executed by the CPU, and Minetest does not use them.
The OpenGL wiki recommends that we do not use this functionality in our program.

-	For DX8 programs, the will always input registers look like this: v0:
-	position, v1: normal, v2: color, v3: texture coordinates, v4: texture
-	coordinates 2 if available.
-
-	For DX9 programs, you can manually set the registers using the dcl_
-	statements.
-	\param pixelShaderProgram String containing the source of the pixel
-	shader program. This can be 0 if you don't want to use a pixel shader.
-	\param callback Pointer to an implementation of
-	IShaderConstantSetCallBack in which you can set the needed vertex and
-	pixel shader program constants. Set this to 0 if you don't need this.
-	\param baseMaterial Base material which renderstates will be used to
-	shade the material.
-	\param userData a user data int. This int can be set to any value and
-	will be set as parameter in the callback method when calling
-	OnSetConstants(). In this way it is easily possible to use the same
-	callback method for multiple materials and distinguish between them
-	during the call.
-	\return Returns the number of the material type which can be set in
-	SMaterial::MaterialType to use the renderer. -1 is returned if an
-	error occurred. -1 is returned for example if a vertex or pixel shader

Subject: [PATCH 37/45] Workaround for too old GL header on older SDL versions

Problem: Since the removal of !_IRR_OPENGL_USE_EXTPOINTER_ we require some quite recent
symbols to compile the legacy GL driver. (*) Since the previous commit we prefer including
them via SDL but those are sometimes too old.

(*) This was in fact always a problem since USE_EXTPOINTER is the default.
    I guess people just had recent enough headers usually.
