We're in a SCREEN 0, text-only screen mode, and yet we're still displaying and animating a graphical box across the screen pixel by pixel!!
How the BLEEP is that possible??
It's because QB64 has a completely separate and independent hardware layer, than it has for any of the software layers. SCREEN 0 is software. HWscreen is hardware. The two are 100% independent from each other.
Hardware layers are always the size of the visible screen (640 x 400 pixels in this case), and are always 32-bit color screens. It doesn't matter if you _COPYIMAGE a 256-color screen into a hardware image, it's automatically converted up to 32-bit colors. Draw on whatever software screen which you prefer; when you're ready to turn it into a hardware image, just call _COPYIMAGE and let it automatically handle the conversion for you.
Adding `_DISPLAYORDER _HARDWARE, _SOFTWARE` above the `DO` loop is a great way to show that rendering z-order layers. This shows the software layer on top?
Switching to `_DISPLAYORDER _SOFTWARE, _HARDWARE` brings back the hardware on top?
Also should go in wiki.
