Template for creating a VFC source file from data captured by one of the EDID utilities (such as SwitchResX).

To use the template completely replace the bracketed comments with the requested data; as an example:
HorizontalBackPorch     = <Back Porch value from Horizontal field of EDID> pixels;
HorizontalBackPorch     = 148 pixels;

When complete, save the template using the descriptive format name used, appended with a ".vfs" file extension.
