TO DO:  (in rough order of priority?)

Fix locking.

DOS version.

Mutli-client streaming version.

G2 pixel is probably unmasked intensity, not a second green.  (The specs
are wrong.)  Fix this in imager.C.

Take advantage of incorrect G2 pixel to use 24bpp to make 32bpp-like
interpolated images at 75% of the cost.

Time/label stamp in imager.C.  Maybe other niftiness like rounded corners,
faded edges, or mst3k heads.  :)

Selectable priorities?  
Generalize webcam output formats, make gtkcam read from webcam.

VIDEC compression and RAM table support will be implemented immediately if
they ever become possible.

Quickcam VC support (parallel only for now), if it ever becomes possible.
