Another demo for the PicoVision; this time exploring the C(++) API instead of MicroPython.
This simply renders some randomly generated line trees, with a day/night cycle as a background.
The moon and sun use hardware sprites; leaves brighten during the day to make them stand out a bit better at midday. Stars come out at night.
Rendering is kept minimal - the trees are only redrawn when they grow, or when the background has changed - because the PicoVision really doesn't like drawing a lot of (non-horizontal) lines.
The graphics are all mine, and are ... terrible. Sorry. Apart from the bird, that I stole from @Gadgetoid's "floppy birb" example.
The sprites are compiled into cpp/hpp files with the pv_image.py script,
which is cannibalised from a script doing a similar job for the PicoSystem.
