gltexture: Restore previous GL context

Browse Source 
Texture downloads can be initiated due to the weirdest reasons - and if
they cause a GL context to be changed, it'd be basically unpredictable
when the GL context changes.

An example is the Cairo renderer - if it needs to draw a GL texture, it
will download it.

Now that no longer changes the GL context.
