but does it rotate. like the planet texture
Not by default, but you can use the TD flag with a number to make it revolve every X days.
RetroEarthDrawer.exe TD 1 - rotates once around the planet per day, keeping the view synced at one specific time of day.
I'm also going to add an option to scale the image up in size. Then I'll post the fixed version, which includes resyncing TD with the actual rotation of the sun.
