				foreground.c

Purpose:
	Execute  foreground command:  change the main window foreground
	color. 

Input:
	(1) Pointer to MolComplexS structure, with macromol. complexes.
	(2) The number of macromolecular complexes.
	(3) Pointer to RuntimeS structure, with some runtime data.
	(4) Pointer to ConfigS structure, with configuration data.
	(5) Pointer to GUIS structure, with GUI data.
	(6) Pointer to NearestAtomS structure.
	(7) The number of pixels in the main window free area.
	(8) Pointer to refreshI.

Output:
	(1) Log file created.
	(2) Return value.

Return value:
	(1) Positive (command) code on success.
	(2) Negative (error) code on failure.
