/// !!!Purpose
///
/// Provides simple drawing function to use with the LCD.
///
/// !!!Usage
///
/// -# Use LCDD_Fill to fill the LCD buffer with a specific color.
/// -# Draw a pixel on the screen at the specified coordinates using
///    LCDD_DrawPixel.
/// -# Draw a rectangle with LCDD_DrawRectangle.
/// -# Draw a string on the LCD with LCDD_DrawString.
