What does this code do?
- mga_vid is a kernel module that utilitizes the Matrox g200/g400 video
- scaler/overlay unit to perform YUV->RGB colorspace conversion and
- arbitrary video scaling.

mga_vid is also a monster hack.
How does mga_vid work?
- This kernel module sets up the BES (backend scaler) with approriate values
- based on parameters supplied via ioctl. It also maps a chunk of video
- memory into userspace via mmap. This memory is stolen from X (which may
- decide to write to it later). The application can then write image data
- directly to the frame buffer (if it knows the right padding, etc).

How do I know if mga_vid works on my system?
- There are test applications called mga_vid_test_g400 and mga_vid_test_g200.
- Use the appropriate one for your card. This test code should draw some
- nice 256x256 images for you if all is working well.
