/**********************************************************
* Function Name: lcd_print_stringXY
**********************************************************
* Summary: prints a string to the LCD screen at a specified
* XY location in specified foreground and background colors
* X will specify the number of characters across with X=0
* being the left most character position, and X=20 being
* the right most.  Y will specify the number of characters
* down the screen with Y=0 being the top of the screen and
* Y=19 being the bottom row of characters.  NOTE: There should
* be a 4 pixel offset in the X location.  The font is 11 pixels
* wide and we have 21 characters across 21*11 = 231 which leaves
* 9 pixels remaining in screen width.  We will have a padding of
* 4 pixels on the left and 5 pixels on the right.  NOTE: none
* of the hard numbers mentioned here should be used.  There
* are macros defined: CHAR_COLUMNS, CHAR_ROWS, X_PADDING in
* the associated .h file that should be used.
* Returns: Nothing
