Version 0.5
-----------
Now works with both the color AND the greyscale QuickCam!
Rewrote much of the code to be more sane
Started playing with a multi-threaded approach

Version 0.6
-----------
Much more versatile code; gqcam should now work with a wider range of
cameras (specifically with CPiA, in general with any the supports the
read() command)
Added a menu with gobs of commands
Added a tear-off control panel
Made things a little faster and a little less CPU intensive.

Random bug fixes (and probably introductions...)

Fixed problem with --dump and no X server running

Version 0.8
-----------
Added some very early filter support
Added a filter to switch the image from BGR to RGB before displaying
(access it through the -s or --swap command line switches for the moment;
in the future there will be a "filters" dialog)
Added a generic error dialog function to make things more visual
Added/fixed up timer support (use gqcam as a webcam!)
Probably a few other little things I am forgetting to list

Version 0.9
-----------
Added a preferences dialog (small now, will grow as time goes on...)
Added an autobrightness option
Added filename timestamp abilities
