This is a simple tool for setting LCD timings on Wiz, which can be used
standalone (from launcher scripts, for example) or compiled into your program
if you are writing one. It accepts a string which contains timing values, for
example:

  'lcd_timings=397,1,37,277,341,0,17,337;clkdiv0=9'

'lcd_timings' specifies display timings (htotal,hswidth,hastart,haend,vtotal,
vswidth,vastart,vaend) which are written directly to chip registers. clkdiv0
is the pixel clock divider.

If you use this in your program, you can keep that string in config file,
environment variable, etc, and pass it to this code. The idea is to keep it
in user editable form in case it doesn't work for everyone or somebody prefers
something different.
