/** \addtogroup lcdd_draw Drawing On LCD
 *
 * Interface for drawing function on LCD.
 *
 * \note Before drawing, <b>canvas</b> should be selected via
 *       lcdd_select_canvas(), or created by lcdd_create_canvas().
 *
 * Following functions can use:
 * - Simple drawing:
 *   - lcdd_fill()
 *   - lcdd_draw_pixel()
 *   - lcdd_read_pixel()
 *   - lcdd_draw_line()
 *   - lcdd_draw_rectangle(), lcdd_draw_filled_rectangle()
 *   - lcdd_draw_circle(), lcdd_draw_filled_circle()
 *   - lcdd_draw_image()
 * - String related:
 *   - lcdd_draw_string()
 *   - lcdd_get_string_size()
 *
