//// graphics.c ////
//// ////
//// This file contains functions to draw lines, rectangles, bars, ////
//// circles and text to a display. A function which draws a ////
//// single pixel must be defined before calling the functions in ////
//// this file. Call it glcd_pixel(x, y, color) where x is the ////
//// horizontal coordinate, y is the vertical coordinate, and ////
//// color is 1 bit to turn the pixel on or off. ////
//// ////
//// * Note: (0, 0) is treated as the upper left corner ////
//// ////
/////////////////////////////////////////////////////////////////////////
//// ////
//// glcd_line(x1, y1, x2, y2, color) ////
//// * Draws a line from the first point to the second point ////
//// with the given color ////
//// - color can be ON or OFF ////
//// ////
//// glcd_rect(x1, y1, x2, y2, fill, color) ////
//// * Draws a rectangle with one corner at point (x1,y1) and ////
//// the other corner at point (x2,y2) ////
//// - fill can be YES or NO ////
//// - color can be ON or OFF ////
//// ////
//// glcd_bar(x1, y1, x2, y2, width, color) ////
//// * Draws a bar (wide line) from the first point to the ////
//// second point ////
//// - width is the number of pixels wide ////
//// - color is ON or OFF ////
//// ////
//// glcd_circle(x, y, radius, fill, color) ////
//// * Draws a circle with center at (x,y) ////
//// - fill can be YES or NO ////
//// - color can be ON or OFF ////
//// ////
//// glcd_text57(x, y, textptr, size, color) ////
//// * Write the null terminated text pointed to by textptr with ////
//// the upper left coordinate of the first character at (x,y) ////
//// Characters are 5 pixels wide and 7 pixels tall ////
//// - size is an integer that scales the size of the text ////
//// - color is ON or OFF ////
//// * Note - This function wraps characters to the next line ////
//// use #define GLCD_WIDTH to specify a display width ////
