[PD] read from multiple web cams , tile then into one image

[yukio kuroiwa]

we want to read from multiple cameras, tile them into one image, then
feed it to pix_multiblob. i had thought of rendering to a few rectangles
and then using pix_snap, but i think that might be slow and it might not
work
 unless the gem window is on-screen (as the graphics card sometimes
 takes shortcuts if it thinks it can). are there any ways to do this
 using just pix_... calls?

many thanx
