The animation of the
simple_menu used in the main menu had the issue that there is a black line visible at the top. This is due the
gfx_puts method ignoring lines, where the top pixel of the string is above the top of the screen. As
gfx_setpixel which in turn ignores pixels outside of the screen, I removed the check in
I also removed the ranges from the documentation of the individual python functions and added a general documentation about the screen and it's ranges.
