Comment(by jyavenard at gmail.com):

 Following talks with Mark Kendall:

 -Reformat the code to MythTV's coding guidelines
 -If framerate > 24.5 fps and < 30.5 fps, then try 2X refresh rate first.
 This is to make sure 50 or 60Hz interlaced video use 50Hz or 60Hz
 progressive refresh rate first. Otherwise if the TV advertises 25 or 30Hz
 progressive, previously this is what Myth would use
 -Add explanation of the meaning of "Any" in the Settings -> Appearance
 configuration screen
 -Change the Settings screen to use floating points for refresh rates
 rather than integers.
 -Use type "double" instead of "float" to be consistent with the data type
 used in DisplayRes class (use same type as for the aspect ratio)

 Ideally, you would want to handle interlaced screen differently, but as
 there's no good support of interlaced screen in Myth or Xrandr, probably
 better to handle this in a separate patch.
