Screen device sprite coordinates should be treated as 16-bit signed #4

Closed randrew closed 2 years ago

An undocumented feature of Varvara screen device is that sprite coordinates should be treated as 16-bit signed, so that they can be drawn past the left or top edge of the screen and bleed into the visible area of the screen. Not implementing this feature causes issues in Noodle when the canvas drawing window is the dragged past the left or top edge of the screen.
