OK the leaves are more satisfactory in my eyes and experience.
Fall banner bplus 2023-09-05A
Less leaves and way less falling leaves so a set will run much longer, 2500 loops instead of 1500, to get barer trees before switch.

' 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
' tweak numbers for falling leaves for more and not too leaden.
' 2023-09-03 FontFlag to signal FPrint is done
' 2023-09-04 do not stop leaves falling when on a tree trunk
' Ran into problems with QBJS handling Point see commented code in MoveLeaf
' So this keeps moving leaves without Point
' Clean up code a bit fix letters shadows, toss junk subs
' Aha! found a way to get leaves off tree trunks = redraw trunks!
' New Type Tree
' 2023-09-05 fix wind so it is continuous between 0 and .5?
' less leaves too
