Graphics on BangleJS2

Having to deal with these weird details is fun

can't argue with that! :)

I was under the impression that it doesn't do a quick blit from that to the framebuffer

In the case where it's a normal Graphics instance and it's not clipped/scaled/rotated there is a reasonably fast path for rendering - it's not quite as fast as it could be, but it's not too bad.

Before writing to the framebuffer I call g.drawRect

Ok, great! Yes, that would ensure it's waited.

And yes, getTime/Date.now use the same underlying timer - they're only accurate to 1/32768 sec on the Bangle, but I imagine that's still enough for benchmarking frame draw times!

And I can imagine about the C/JS difference - the JS interpreter is going to be at least 100x slower than C I imagine
