Method assert_xy_in_range

std/src/gfx/lcd/buffered/mod.rs:186–193

Make sure that the coordinates are within the LCD space. This is only used to validate input parameters for those functions that are internal to the console (such as `move_pixels`). Functions subject to user input (such as `draw_rect`) must not use this.
