This started out as a warning about a shadowed global variable but turned out
to be an unused global variable as the one in local scope handles all cases.
i found that generic loaders broke on my machine. stdout was never
reaching the app. child process exited and never sent stdout before
parent got anything - it all was lost in buffers somewhere. this fixes
it. fflush stdout. nasty little bugger.
@fix
With 0.31 poppler removed some parts of GlobalParams
which they do not consider a public API. The antialias
setting can now be done over the output device.
Fixes T2184

Be aware this is quite heavy and for some reason terminology seems to trigger
quite a lot of try here. The generic infrastructure could be improved and use
a cache of generated pdf (right now to display one image, we will generate
the pdf at least 2 times !).
