/*
* NAME: WriteCharDisplayBuf
* DESCRIPTION: Writes one character to the display screen buffer (DisplayUpdate() needs to be called subsequently to output the buffer to the screen)
* INPUTS:
*
* Character: The character we want to draw. In this sample, special characters like tabs and newlines are not supported.
* Col: The horizontal column we want to start drawing at. This is equivalent to the 'X' axis pixel position.
* Row: The vertical row we want to write to. The screen is divided up into 4 rows of 16 pixels each, so valid values for Row are 0,1,2,3.
*
* RETURN VALUE:
* We return the number of horizontal pixels used. This value is 0 if Row/Col are out-of-bounds, or if the character isn't available in the font.
