Functions

• obj:bounds( int min, int max )
• obj:clamp( int val ) ==> int newVal

  clamps value to range

• obj:format() ==> str val

  if step value zero then %g format
  else %.*f format w/ digits for step value

• obj:increment( int value, int n ) ==> int newVal

  adds (n times step) to value
  if step 0, use (max - min) / 100

• obj:range( int min, int max )

  clamping is done after rounding to step value

• obj:round( int val ) ==> int newVal

  Round to nearest step increment
  Does nothing if step is zero
