+/// !!!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.
