USB Webcam on Linux

This is a simple program which reads a stream of images from a USB webcam and displays it on the screen. Version 1.1 and on can capture an image and save it on disk.

• Initial version is an old one based on old gfx library. It can handle a rather old Logitech webcam and not much else.
• Version 1.0 is based on gfx-2.10. It can handle Inca-467 webcam with S920 picture format.
• Version 1.1 is based on gfx-2.11. It handles the MJPG image format as well as higher resolutions. I tested it with a A4Tech PK-910H webcam and it works OK.

I learned one thing about the MJPG format: It's just JPEG. Sure, it doesn't have JFIF or JPEG ASCII magic at the beginning, but libjpeg can decode it without any problems.
