Fib vector tuning

FEATURE_FIB_VECTOR_GET_SIZE_WITH_VARIABLE added

With this feature the Fib vector class @see cFibVector will use a variable
to get the size of the underlying vectors. This will speed up the
Fib vector speed up.

convertFibToFibPointList parameters for output

Parameters to remove duplicates and to sort the points added:
	-remove_duplicates or -rd
		duplicate points will be removed;
		if ther are two equal points in the evalued point list the
		first will be removed with all its properties
	-sort_position_data or -s
		the evalued point list will be sorted;
		duplicate points will be removed and the properties of duplicate
		points merged
convert RGBA scaled

Now it is posible to convert RGB or RGBA pictures from Fib, which have
other property domains than natural numbers with 8 bits.
