For detailed timings, add front porch, pulse width, and back porch numbers in parenthesis (smaller integers are easier to comprehend, useful when comparing or editing timings in SwitchResX or other custom timing editors, negative values will be more apparent - this can happen for back porch when offset and width exceed total blanking).
Also, add missing VertFreq and HorFreq values to DisplayID type 1 timings.
