[GEM-dev] QT for windows

[Daniel Heckenberg]

Hi all,

I've added a [pix_filmQT] object which is a slight reworking of the
pix_filmDarwin to work with QT for Windows.

As the name suggests, I'm hoping that we can have a single source base for
QT on Windows or Darwin...  in fact I've tried to ensure that pix_filmQT
should compile and run on Macs... my changes are very slight indeed.

It's not based on the newer film object scheme as I still haven't had a
chance to look into how that all works.
