I'm afraid we can't change existing ioctls for backward binary

Maybe a new ioctl should have (mostly similar with rasops_info):
- width per pixels
- height per pixels
- depth in bits
- stride in bytes
- ptr for mmap()
- number of bits for red (for 15/16/24/32 bits per pel)
- number of bits for green
- number of bits for blue
- which bit red starts at
- which bit green starts at
- which bit blue starts at
- some bitblt functions (copy, fill etc.?)
and more?
