Fix, NSPrintOperation

[Georg Fleischmann]

Hi,

here is a patch for [NSPrintOperation (GSEPSPrintOperation) -createContext:].
I fixed the problem before (in a different way), but it's now back again.

The problem is, that GSStreamContext doesn't close it's file stream before the  
application has returned to the runloop, but the contents of the file is  
needed earlier in deliverResults.
The patch adds a local AutoreleasePool for the EPS context to get rid of the  
autorelease.
