-Adapters are used to communicate between virtual hardware and the browser (or
-nodejs, or anything else). Currently, there are 3 adapters: Keyboard, Mouse and
-Screen. Adapters are passed through `settings.keyboard_adapter`,
-`settings.mouse_adapter` and `settings.screen_adapter` respectively, but they
-can also be undefined. 
-
-Here is a list of functions that must be implemented by adapters:
-
-**ScreenAdapter:**
-
-- `put_pixel(x, y, color)`
-- `put_pixel_linear(offset, color_part)`
-- `put_char(row, col, chr, bg_color, fg_color)`
-- `update_cursor(row, col)`
-- `update_cursor_scanline(start, end)`
-- `clear_screen()`
-- `timer_graphical()`
-- `timer_text()`
-- `set_mode(is_graphical)`
-- `set_size_graphical(width, height)`
-- `set_size_text(rows, cols)`
-- `destroy()`
-
-**KeyboardAdapter:**
-
-- `init(send_code_fn)`
-- `destroy()`
-- `enabled`
-
-**MouseAdapter:**
-
-- `init(click_fn, move_fn, wheel_fn)`
-- `destroy()`
-- `enabled`
-
-**More**
-
-In addition to adapters, the following functions must be provided in global
-scope (TODO: Improve that).
-
-- `next_tick()`
-- `set_tick(fn)`
-- `log(str)` - only in debug modes
