SUMMARY
	Name	int positiv
	Type	Input
	Inputs	NONE
	Outputs	intpositiv - 	integer
	alpha - 	real

	Parameters
	Name		Type	Default	Choices
	min alpha	dial	 0.25	 0.00	 1.00
	downsize	idial	1	1	8

DESCRIPTION
        This is a short module to adjust the 'tracer' to 'downsize'.
        It works in connection with 'downsize points'.
        The first parameter is a replacement of 'integer'.
        Only positive values are allowed.
        The second parameter is multiplied with the first to give an 
        adjustment of the alpha value in 'tracer'.
        Now it is possible to use 'downsize' with the 'tracer'.
        The size and the opacity of the image is independent from 
        the downsize value.

INPUTS

PARAMETERS

min alpha (dial)
        basic alpha value for 'tracer' if downsize is = 1

downsize (idial)
        positiv integer for 'downsize' and 'downsize points'

OUTPUTS
	intpositiv - integer
	alpha - real
