testgdk.c

[John Emmas <johne53 tiscali co uk>]

Inside the 'gdk' source directory there's a file called "testgdk.c".  Is 
it considered to be up-to-date?  In other words, if I build it, should 
the tests pass?
Having recently built gdk from source (on Windows 7, 32-bit) I decided 
to compile and run that module, just to see what happens - but a couple 
of the tests are failing.  I don't mind digging a bit deeper because 
it's entirely possible that there's something wrong with my build - but 
up to now, test failures have usually been due to the test sources being 
slightly out of date.  One test which seems to always fail is the test 
at line 493:-
    case GDK_NOR:
      QTEST (newpixel == (~oldpixel & ~mask));

but there are others too which I haven't tracked down yet  :-(
