Martin Gräßlin fdd804bdf4 Remove GL context creation from CompositingPrefs
Whether creating the OpenGL context succeeds or not
had no influence in any decisions on the used settings
for OpenGL based compositing.

The only valid information CompositingPrefs still detects
is whether direct rendering should be used which is
performed out of process and does not require a context.

So overall the context creation is not needed and can
be removed.
