pix_x.i4.v = lx_col_to_pix(column.i4.r [,max_column.i4.r]

	pix_x.i4.v = lx_col_to_pix_c(column.i4.v [,max_column.i4.r]

	This routine is converts a character cell column value to an X
	coordinate on a graphics screen.

	column		column to be converted
	[max_column]	maximum number of columns possible
	[text_size]	text size to calculate for (default is current size)

	This function returns status values as follows:

	CBS_RANGE		column value is out of range
	otherwise		corresponding pixel value

	This function requires the following include files:

	cbslib_h, acnet_errors_h
