* print_line_from_here_to_there() takes two cartesian coordinates and draws a line from one

* is the present location of the nozzle. We don't necessarily want to print from this location.
* We first need to move the nozzle to the start of line segment where we want to print. Once
* there, we can use the two coordinates supplied to draw the line.
*
* Note: Although we assume the first set of coordinates is the start of the line and the second
* set of coordinates is the end of the line, it does not always work out that way. This function
* optimizes the movement to minimize the travel distance before it can start printing. This saves
* a lot of time and eliminates a lot of nonsensical movement of the nozzle. However, it does
* cause a lot of very little short retracement of th nozzle when it draws the very first line
* segment of a 'circle'. The time this requires is very short and is easily saved by the other
* cases where the optimization comes into play.

* print_line_from_here_to_there() takes two cartesian coordinates and draws a line from one

* is the present location of the nozzle. We don't necessarily want to print from this location.
* We first need to move the nozzle to the start of line segment where we want to print. Once
* there, we can use the two coordinates supplied to draw the line.
*
* Note: Although we assume the first set of coordinates is the start of the line and the second
* set of coordinates is the end of the line, it does not always work out that way. This function
* optimizes the movement to minimize the travel distance before it can start printing. This saves
* a lot of time and eliminates a lot of nonsensical movement of the nozzle. However, it does
* cause a lot of very little short retracement of th nozzle when it draws the very first line
* segment of a 'circle'. The time this requires is very short and is easily saved by the other
* cases where the optimization comes into play.
