* Standard Version: 1.0, Revision: 1.0
*
* The GTF Document contains the following Copyright information:
*
* Copyright (c) 1994, 1995, 1996 - Video Electronics Standards
* Association. Duplication of this document within VESA member

*
* While every precaution has been taken in the preparation
* of this standard, the Video Electronics Standards Association and
* its contributors assume no responsibility for errors or omissions,
* and make no warranties, expressed or implied, of functionality
* of suitability for any purpose. The sample code contained within
* this standard may be used without restriction.
*
*
*
* The GTF EXCEL(TM) SPREADSHEET, a sample (and the definitive)
* implementation of the GTF Timing Standard, is available at:
*
* ftp://ftp.vesa.org/pub/GTF/GTF_V1R1.xls
*
*
*
* This program takes a desired resolution and vertical refresh rate,
* and computes mode timings according to the GTF Timing Standard.
* These mode timings can then be formatted as an XFree86 modeline
* or a mode description for use by fbset(8).
*
*
*
* NOTES:
*
* The GTF allows for computation of "margins" (the visible border
* surrounding the addressable video); on most non-overscan type
* systems, the margin period is zero. I've implemented the margin
* computations but not enabled it because 1) I don't really have
* any experience with this, and 2) neither XFree86 modelines nor
* fbset fb.modes provide an obvious way for margin timings to be
* included in their mode descriptions (needs more investigation).
*
* The GTF provides for computation of interlaced mode timings;
* I've implemented the computations but not enabled them, yet.
* I should probably enable and test this at some point.
*
*
*
* TODO:
*
* o Add support for interlaced modes.
*
* o Implement the other portions of the GTF: compute mode timings
* given either the desired pixel clock or the desired horizontal
* frequency.
*
* o It would be nice if this were more general purpose to do things
* outside the scope of the GTF: like generate double scan mode
* timings, for example.
*
* o Printing digits to the right of the decimal point when the
* digits are 0 annoys me.
*
* o Error checking.
