WARNING: very minimally tested
In general you should not need this tool. Its primary purpose is for
benchmarking, and for debugging performance issues.
For many kernel releases now sysfs has supported reading and writing the GPU
frequency. Therefore, this tool provides no new functionality. What it does
provide is an easy to package (for distros) tool that handles the most common
scenarios.
v2:
Get rid of -f from the usage message (Jordan)
Add space before [-s (Jordan)
Add a -c/--custom example (Jordan)
Add a setting for resetting to hardware default (Ken)
Replicate examples in commit message in the source code. (me)
v3:
Its not It's (me)
Add --help/-h to usage
Add Version + man page
Rename tool to intel_gpu_frequency, from intel_frequency
Remove "sudo" from the examples

The tool allows you to change the panel fitter settings, so you can
change the size of the screen being displayed on your monitor without
changing the real pixel size of your desktop. The biggest use case for
this tool is to work around overscan done by TVs and some monitors in
interlaced mode.
v2: reviews by Ben, Chris and Rodrigo
- don't install
- use intel_register_access_init
- check for maximum X and Y values
- add a disclaimer saying this is not the real solution
- print less when pf is disabled and option '-l' is used

The patch coverts the man subdir to the standard xorg man page makefile.
The version number is automatically updated when a new release is made.
The man page section number is no longer hard coded either.
The package util-macros at version 1.8 or greater is required.
