-/*
- this is an attempt at a Linux version of pix_video by Miller Puckette.
- Anyone conversant in c++ will probably howl at this. I'm uncertain of
- several things.
-
- First, the #includes I threw in pix_video.h may not all be necessary; I
- notice that far fewer are needed for the other OSes.
-
- Second, shouldn't the os-dependent state variables be "private"? I
- followed the lead of the other os-dependent state variables. Also,
- I think the indentation is goofy but perhaps there's some reason for it.
-
- Third, I probably shouldn't be using sprintf to generate filenames; I
- don't know the "modern" c++ way to do this.
-
- Fourth, I don't know why some state variables
- show up as "arguments" in the pix_video :: pix_video().
-
- This code is written with the "bttv" device in mind, which memory mapes
- images up to 24 bits per pixel. So we request the whole 24 and don't
- settle for anything of lower quality (nor do we offer anything of higher
- quality; it seems that Gem is limited to 32 bits per pixel including
- alpha.) We take all video images to be opaque by setting the alpha
- channel to 255.
