' started 2017-10-21 by bplus as: fall foliage.bas SmallBASIC 0.12.9 (B+=MGA) 2017-10-21
' 2023-08-30 start of QBJS Banner
' 2023-08-31 Logo and Hills added
' 2023-09-01 Fellippe I see contributed allot to orig code with moving leaves
' Also thanks to grymmjack for getting me starting of PFont and font patterns.
' Also thanks to dbox for catching all my errors with QBJS.
' 2023-09-03 try to fix font print to print while leaves are falling
