History List

  The basic idea here is that we want to keep as much history as we can without paying 
a high price in terms of memory space.  Because we keep the history for display purposes, 
we can take advantage of the fact that when the period shown in the graphs is long 
then each pixel represents a long period.  So as the most recent history we keep one 
window full of points at a resolution of 1 second, the next window full at 2 seconds, 
the next at 4 seconds and so on, up to the maximum desired.  This way there is always 
at least one sample point per pixel for any update delay set by the user, and the 
memory required grows with the *log* of the total time period covered.
  The history is kept in a doubly-linked list, with the most recent snapshot at the tail.  
The number of nodes in the list is fixed, and there are no calls to RemoveHead() and 
AddTail() which would add overhead and contribute to memory fragmentation.  Instead, 
every second when a new point gets recorded, one of the existing nodes is recycled; 
it is disjoined from its present place, put at the tail of the list, and then gets 
filled with new data.   [Emilio Sandoz]
  This unfortunately does not work with stl classes, as none of them supports moving
a node to another place, so we have to erase and re-add nodes.
*/

void CStatistics::RecordHistory()
{	// First we query and compute some values, then we store them in the history list
	
	// A few comments about the use of double and float in computations:
	// Even on a hi-res screen our graphs will have 10 bits of resolution at most,
	// so the 24 bits resolution of a float on 32 bit Intel processors is more than
	// enough for all displayed values.  Rate computations however, and especially 
	// running average computations, use differences (delta bytes/ delta time), and 
	// for long uptimes the difference between two timestamps can lose too much 
	// accuracy because the large mantissa causes less significant bits to be dropped
	// (same for the difference between two cumulative byte counts).  [We don't store 
	// these values as integers because they will be used in floating point calculations,
	// and we want to perform the conversion only once).  Therefore timestamps and 
	// Kbyte counts are stored in the history as doubles, while computed values use
	// float (to save space and execution time).
