FLIP 0.9

A nice screen hack that rotates your screen.

Usage:

  flip -s <speed in percent> -n <number of rotations> -i (for info about 
  your video card) -h (for help)

Example:

  flip
or
  flip -s 50 -n 5 -i


Limitations:

  Requires a video card with an aperture at least the size of the screen.
  E.g. a VL-bus or PCI-card. Also, the ATI-mach 32 can have this aperture
  mapped on the ISA bus, but that will probably be too slow.
  I think it needs also a math co-processor, but this is easily fixed
  by recompiling the sources.

  I'll fix support for bank-switched cards and the math-coprocessor 
  requirement in a later version. 

Based on:

  ftp.cdrom.com:pub/os2/2_x/programming/dive.zip

  This file contains info on how you program to write directly to the
  frame buffer. This technique is used in flip to get the speed it needs.

  It's just for fun !! :-)
