Patches from James H. The usual stuff (memory leak fixes and 16-bit

cleanliness), plus he's enlarged the pencil-mark circles from
TILESIZE/8 to TILESIZE/7. Makes no difference at all (thanks to
integer division) when TILESIZE is the default of 20, but presumably
helps at some other tile sizes. Fine by me.
