- Add a good comment explaining how the windows part of the module was implemented... what's the idea behind it.
- Something like, Since windows provides a single input buffer with all events, we need to peek through them and
- discard the ones that are of no use for us.
- Because it's a single buffer, all functions need to do repeated work (see if it's resize, see if it's a key press)
- ... and so on.
+ /*
+ The Windows API provides all input events (keyboard, mouse, window resize) on a single input buffer.
+ To make it match this module's API, we need to do some pre-processing while waiting for input.
+ This means that OS_wait_for_input will peek at the input events, signal if a window resize is found,
+ and discard unwanted events (like button release events).
+ A similar logic is applied in OS_read_input.
