Method assert_xy_size_in_range

std/src/gfx/lcd/buffered/mod.rs:200–218

Make sure that the coordinates and size 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.
